It has been 26 days since Khan along with Pakistan Awami Tehreek chief Tahirul Qadri and thousands of supporters began protesting in the capital, seeking the resignation of PM Sharif over what they claim was massive rigging of the 2013 general elections.
The protest movement has lost momentum since August following clashes with police that left three dead. Speculation that the powerful army may step in to intervene, as it has in the past, reached fever pitch when protesters stormed state broadcaster, PTV.
Since then, opposition parties inside Parliament have backed Sharif, lowering political temperatures as negotiations with the protesters were restarted and attention shifted to the devastation wrought by monsoon floods.
Only a few hundred protesters, dressed in green and red shawls and hats of Khan's PTI are now permanently camped at the site while the two sides attempt to negotiate a settlement to the impasse.
By night however, their numbers swell to thousands as men, women and children dance to patriotic songs between the 61-year-old's speeches in an atmosphere similar to a rock concert.
In an interview with AFP from inside a shipping container converted into a makeshift room, Khan he vowed to fight on until he toppled parliament - which he called a "coalition of crooks".
"I've got a feeling it's not that far (to go). I think it's a battle of nerves. It's a matter of who buckles under the pressure first. I've got a feeling we'll win it,” he said. "The sticking point is always going to be Nawaz Sharif. We have no confidence in him."
Khan also came under fire over the storming of PTV by people wearing the colours of his party and Qadri's that raised fears that the protest leaders were attempting to involve the army.
But after initially apologising for the event and saying his party workers had "become emotional", Khan told AFP the whole affair had been staged by the government to discredit him.
"It was an inside job and there are cameras there that can easily identify the people responsible. We're challenging them to identify those people," he said.
Such about-turns are not new for Khan - who has accused senior judges whom he once supported of helping to rig the elections, and was vocally against an operation against Taliban militants in the northwest before backing it once the army began its action.
And despite Khan's insistence that his supporters are non-violent, he has used heated rhetoric, such as calling for Sharif to be grabbed by the throat and dragged out of his residence.
But his appeal endures thanks to the growing politicisation of the country's urban middle classes, who are repulsed by the traditional dynastic parties.
Though local and foreign observers rated the 2013 polls as relatively free and fair, the government's initial reluctance to act on Khan's demands have fuelled suspicion it may have something to hide.
"It's an illegitimate government. What matters to me more than anything else is the sanctity of every single vote," said Jawad Haroon, a former university professor from Lahore who had come to support Khan's protest.

@Uzair aftab-qureishi: My dear Brother I have nothing to do with the internal matters of Pakistan, but one thing is strange the same Election Commission conducted the elections in KPK and here you think the elections were fair because PTI was able to form the Govt and in other parts where they lost the elections were rigged is not it a double standards, kauri kauri thoo methee methee harapp.
I was trying to pretend like neutral guy as I am representing media but I am really shocked.... What a temperament Imran Khan has ???? I don't know whether this movement is going to successful or not but I am sure that it will stop here..... there will be no hope for common man in Pakistan
Why is this a "battle of nerves" ? The battle is over. Only Imran Khan does not realize it.
@humza If Punjab is so well governed, why is there sudden population growth? Where's my electricity?? I pay taxes, where is it?? Only 39% of children go to school in Punjab, know that's less than KPK. Why Were there over 90 constituencies with excess votes? Meaning more votes than the registered population. Answer???
@Uzair aftab-qureishi: I see from your posts you think anyone who disagrees with you is either "silly or a corrupt zamindar". I can assure you that I am not either. I support stable democracy in Pakistan but I don't buy into quick rich schemes to make money any more than I buy into quick change schemes for governments or ruling a country. These Third World concepts of quick money and quick fixes are nothing but delusions. Working within a system and letting a system mature over several cycles requires patience and hard work. Only when Pakistanis learn to respect that it is better work within an imperfect system than to create anarchy, the nation will move forward. For the record, I supported PTI until its current antics and violent protests. I no longer support Imran Khan although I respect his charity work. My parents and their generation supported PML N because they see them as economy driven and keen to upgrade motorways, rail links Gwader etc. We can all agree to disagree but you cannot deny that Punjab under Shahbaz Sharif is the best governed and developing province in Pakistan floods or no floods. It should come as no surprise that the majority of Pakistanis voted the Sharifs in on this basis alone. The Western analysts who say that elections were largely fair and free despite minor rigging that goes on in all Third World countries are not just making statements. They witnessed the elections too.
@oats
The sharif bros. have ruled Punjab for 30 years, any change? Do they want 40 years? Stop glorifying PMLN, and say the actual facts. PMLN has done nothing, besides pocket 1 billion dollars each year.
@Uzair aftab-qureishi: Tell us how much electricity Musharraf gave us in 10 years dictatorship? The answer is 0 MW to the national energy grid. I could on about how little was done during Musharraf's rule and how he gave us most of our current problems including terrorism and instability. What I can't understand is how you can possibly equate scarcely one year of the current government's rule with a possible fix for everything? Let them finish their mandate and then comment. Western financial analysts were upbeat on the pro economy PML N government until Imran Khan and Tahirul Qadri created unrest. It seems some people don't want Pakistan to develop and and eager to discredit an elected government for their own gains. Fortunately the majority of Pakistan's people stand behind democracy, the government and long term stability for Pakistan. Imran Khan, Tahirul Qadri, their mob of violent protesters and their backers have failed to destabliise Pakistan. It's time for them to stay in their containers and be quiet.
@imm the dim 1. If u look back musharaff's time in power proved to make pakistan better than it had been during the 90s. Investment came, Pakistani was growing economically. So I honestly don't care who was allied with musharaff. 2. He remained clean from previous time as he had no corruption cases. 3. Ex-secretary admitted there was rigging, Punjab ballot boxes came in late, over 90 constituencies had votes which were cast much more than the registered voters. Personally, I went to vote in Lahore, saad rarique and his goons closed the polling stations for the entire period, I was not allowed to cast my vote. PTI also came second in over 90 constituencies and lost to PMLN counter parts by mere 1000-2000 votes on average, coincidence?? 4. Imran endorsed him, because he thought there was going to be actual free and fair elections. In this case I think imran was too naive, after PMLN has shown its true colours before, obviously they were going to cheat. Plus pre-elections polls showed imran and nawaz were 'neck and neck'. How did 50% become 65% in one day???? 5. NS didn't start the operation, it was Raheel sharif. Plus electricity has been going more than zardari's, ramzan was awful, u actually think nawaz is better? 6. Yeah, cause there were no irregularities in KPK. U think nawaz is better, fine, answer this, why hasn't nawaz attended NA sessions in 14 months? Why did nawaz delay 9 months for talks with Taliban? U are either an extremely silly person or literally just another corrupt zamindar to support nawaz.
Go nawaz, I used to support u, now I want imran. PTI WILL DESTROY you and your corrupt party. U have destroyed pakistan enough, now go! GO!
For all the imran haters. PMLN, and PPP have both been in the government previous times. They have both failed miserably. Pakistan was doing extremely well under Musharraf, 'democracy' comes in, PPP destroys pakistan in 5 years. All the hard work by shaukhat aziz is removed, PAKISTAN topped corruption in 2010. PMLN has done nothing in 2013-14, electricity is worse than ever, taxes are so high, our economy is in shambles, and he honsetly rigged the elections. All PMLN supporters, you know he rigged them, do not lie and just be 'so what'. Our country is at stake here, imran may not be an excellent option, but he is still the best out of all the options. KPK has actually improved much more in 1 1/2 year than it had from 2008-2013. If u watch news bought by the media, of course it will look like PTI did nothing. They reduced corruption, increased literacy, and KPK had the most federal government approval throughout Pakistan. So don't say u want PMLN. Fine, if u want a Pakistan like nawaz or zardari's, go and watch your children cry in the heat of a room with no electricity. But if you want pakistan to get better, than I suggest you support imran.
GO Nawaz GO
IK has nothing to do in his life only wasting time of people and govt, what he is doing not good for Pakistan. please go away we are fed up.
