Britain to end 10-year boycott of Narendra Modi
Modi will be in London from November 12 to 14 before heading to Turkey for a G20 summit, an Indian foreign ministry source confirmed to AFP on condition of anonymity.
During the three-day trip, Modi will meet with Britain's leadership and address the country's large Indian diaspora at Wembley Stadium, as well as inaugurate a memorial of India's low-caste icon Bhimrao Ambedkar at his former London house.
The trip is Modi's first since London ended its decade-long diplomatic boycott of the Hindu nationalist in 2012 over deadly anti-Muslim riots while he was running his home state of Gujarat.
