Four parliamentarians with Britain's Labour party have
challenged Prime Minister Gordon Brown for the party's leadership, calling for
internal party leadership elections a week before the annual Labour party
This comes after another member of Brown's government team was fired Friday after pressing for a party leadership election.
Brown's authority has already suffered in recent months after the collapse in electoral support as well as a number of internal party rivalries.
It has been speculated that Brown will have to fight for his political survival at the upcoming conference which is due to take place in the northern English city of Manchester next weekend.
The opposition Conservative party led by David Cameron has for months shown a two-digit lead over Labour in opinion polls, dpa reported.
