Mediator fails to resolve Mayweather-Pacquiao dispute

Manny Pacquiao\'s promoter, Bob Arum said the proposed \'super-fight\' with Floyd Mayweather Junior is off after talks failed to resolve the fighters\' differences.



Pacquiao pulled out of the lucrative contest, which was scheduled for March 13, after Mayweather demanded random drugs tests ahead of the bout.



A mediator was called in to settle the dispute, but after two days the pair failed to resolve their differences.



The \'super-fight\' was likely to have been the richest in boxing history.



With potential purses of up to 25 million pounds per fighter acting as a strong incentive, Former Judge Daniel Weinstein, who had helped resolve previous spats between the pair, was brought in as a mediator.
