In a five-page letter to the election commission, Pacquiao, 37, said that as a candidate for the May elections, he was allowed TV and radio air time for political advertisements and that his fight will not consume all of the allotted time.

The commission on Tuesday said it may bar broadcasts of Pacquiao's bid to win back the world welterweight title next month from reigning WBO welterweight champion Bradley because it could give him an unfair advantage in the elections.
"There is obviously no case of undue advantage or undue exposure for Pacquiao as the same rights and privileges are extended by law to all said candidates," Pacquiao said through his lawyers.
The bout will take a maximum of 36 minutes for a 12-round fight, or less if the fight does not go the distance. Under the law, all candidates are given up to 120-minute TV and 180-minute radio advertisements per station.
Pacquiao's description of gays as "worse than animals" last month drew criticism on social media at home and abroad, and cost him an endorsement deal with Nike, the world's largest sportswear maker.
The election commission is expected to make a ruling on the broadcasts soon.
