Pakistan's opposition announced Friday it will boycott a special session of the National Assembly this weekend called by the prime minister after a politically embarrassing defeat of Imran Khans key candidate in elections for the Senate.

Khan, who enjoys the backing of majority lawmakers in the lower house of parliament, convened the session for Saturday after his candidate lost the race for a seat in the 100-member upper chamber earlier this week.

The Senate elections on Wednesday saw the ruling Tehreek-e-Insaf partys candidate, Finance Minister Hafeez Sheikh, lose against Yusuf Raza Gilani, a former prime minister and senior opposition leader.

Despite Sheik's loss, Khan's party emerged as the largest single party in the Senate but even with its allies from other parties, the opposition still has a slight, 53-47 majority over Khan in the upper chamber.

Following the balloting, the opposition demanded Khan step down but the ruling party rejected the demand and the prime minister called for the confidence vote.

Khan needs 172 votes in the 342-seat National Assembly to retain the confidence of the house on Saturday. If none of his supporters turn against him, he is expected to win as many as 180 votes in his favor, with help from allies from other parties. His own party has 157 lawmakers in the lower chamber.

On Friday, senior politician Fazlur Rehman, who heads the coalition of opposition parties called Pakistan Democratic Movement, announced that the opposition would boycott the session.

Sheikhs defeat was a setback for Khan who even criticized the country's Election Commission, claiming it had failed to ensure a free and fair vote for the Senate and saying that some 15 or 16 lawmakers from his party allegedly sold their vote to the opposition candidate.

Angered over Khan's criticism, the commission on Friday fired back, saying every political party and politician needs to have the spirit to accept defeat when it comes and not resort to mudslinging over election losses.
