Two more British MPs announced they would resign in an expenses scandal which has thrown parliament into crisis, fuelling calls for Prime Minister Gordon Brown to call early elections.

Margaret Moran of the ruling Labor Party and Julie Kirkbride of the main opposition Conservatives said they will step down at the next general election after days of pressure from angry constituents and the media.
Both were among the most notorious cases in the expenses row, which has seen 11 MPs quit since it erupted, including House of Commons Speaker Michael Martin.
Ms Moran claimed 22,500 pounds ($45,700) from the public purse to treat dry rot in one of her homes which was about 160 kilometers from both the House of Commons in London and her constituency.
Ms Kirkbride followed her husband, fellow Conservative MP Andrew MacKay, in quitting after the Daily Telegraph newspaper reported they both claimed allowances for a house they shared, effectively double-charging the taxpayer.
She also faced a string of other damaging claims, including that she used public money to fund an extension to her constituency flat so her brother could stay and help with her childcare.
In her resignation letter to Conservative leader David Cameron, Ms Kirkbride said she had been subjected to a “barrage of distorted press stories”.
Ms Moran continued to deny any wrongdoing, saying she was going because the stories had had “a bruising effect upon my friends, my family and my health”.
The Daily Telegraph has published three weeks of revelations based on leaked documents about how MPs claimed public money for everything from moat cleaning to a duck island.
As the main parties battle to regain public trust after the scandal, a handful of MPs have been ordered by their party leaders to pay back money from expense claims deemed too lavish, while others will have to appear before scrutiny panels which will determine if they have done anything wrong.
Gordon Brown is facing heavy pressure from David Cameron to call a general election soon over the issue. He must go to the polls by the middle of next year at the latest and the Conservatives have a big lead in opinion polls.
“I think it's no good members of parliament thinking they can sort all this out without consulting the public,” Mr. Cameron said. “They want to pass judgment on their members of parliament.”
But experts say the scandal could hit support for both main political parties at European and local election votes being held on June 4.
Professor Patrick Dunleavy of the London School of Economics told reporters at a briefing ahead of the vote that it had caused a “remarkable and in fact unprecedented constitutional crisis”.
Ms Moran's constituency in Luton, central England, is one of a string which looks likely to be targeted by anti-sleaze campaigners hoping to harness public anger at the general election.
Esther Rantzen, a television journalist famous for campaigning on behalf of consumers, has said she will stand for the seat if locals want her to.
At Ms Moran's constituency office on Thursday, someone had daubed the words “That's Life” - the name of the hit 1980s TV show which Ms Rantzen presented.
