Prime Minister's Questions in the House of Commons has been cancelled today following the death of David Cameron's son Ivan.

All political parties this morning agreed to suspend the weekly half-hour sparring session at the dispatch box in favour of brief statements of condolence from senior politicians at midday.

Ordinarily, if Mr Cameron was unable to attend PMQs his place would be taken by shadow foreign secretary William Hague.

However, Number 10 confirmed this morning that after statements by Prime Minister Gordon Brown, Mr Hague, and Lib Dem Treasury Spokesman Vince Cable, who is covering for leader Nick Clegg while he is on paternity leave, the House will be adjourned until 12.30pm, when business will continue as usual.

The last time PMQs was cancelled was in January 2000, after MPs took 29 hours to debate a Bill about the Northern Ireland peace process.
