ISLAMABAD: The Election Commission of Pakistan (ECP) on Tuesday announced that it would probe the allegations of horse-trading in the recently held Senate polls.

In a notification issued, the ECP has summoned all political party heads and leaders who levelled horse trading allegations to appear before the commission with proof on March 14.

Pakistan Muslim League-Nawaz, Pakistan Tehreek-e-Insaf and Muttahida Qaumi Movement-Pakistan have expressed reservations over some political parties bagging Senate seats without having substantial representation in the provincial assemblies.

Speaking to media outside the accountability court on Monday, PML-N Quaid and former prime minister Nawaz Sharif stressed it was crucial to get to the bottom of this issue. ?This game of money should be buried. This has happened in the past, but this time it was too open and brazen.?
