UK leader to defend government record amid Tory civil war

Britain's Prime Minister David Cameron is set to defend his government's record amid an intra-party fight over welfare cuts.

Cameron is expected to respond to the surprise resignation of Iain Duncan Smith, the work and pensions secretary, over plans to cut benefits for the disabled. Duncan Smith says he decided to leave after the latest benefit cuts were "juxtaposed" with tax breaks for the better off.

Cameron appears before the House of Commons on Monday to report back on last week's EU immigration summit. But with headlines describing his party as being locked in "civil war," he is likely to face questions about benefit cuts.

Conservative lawmaker Sarah Wollaston told the BBC that Treasury chief George Osborne should come back to Parliament to revise his budget decisions.
