Sir Malcolm Rifkind steps down as chair of the Intelligence and Security Committee
He also announced he will quit as an MP at the coming election
Both Sir Malcolm and Labour's Jack Straw deny any wrongdoing over 'cash-for-access' allegations
David Cameron announced British military personnel are to be sent to Ukraine to provide advice and training
Green Party leader Natalie Bennett struggled to explain costing of election promises
There are 72 days until the general election
On to today and we're looking forward to the launch of the Green Party's election campaign. The leader, Natalie Bennett, and her as yet only MP, Caroline Lucas, will make speeches outlining key campaign themes and unveil new campaign poster. Ms Bennett will also speak to BBC Radio 4's Today programme this morning - listen via the live tab above.
On Monday, we also learned details of the TV election debates that broadcasters hope to screen in the run-up to 7 May. If - and it's a very big if - they do happen, ITV and the BBC will each host a seven-way ding dong, featuring the Conservatives, Labour, Lib Dems, Green, UKIP, SNP and Plaid Cymru. The final debate, hosted jointly by Sky and Channel 4, would be a head-to-head between the men who would be king - or PM more accurately - David Cameron and Ed Miliband.
The pressure hasn't eased up on the two men, particularly Sir Malcolm Rifkind, who is facing calls to step down as chairman of Parliament's Intelligence and Security Committee. His predecessor, Kim Howells, said the allegations would make Sir Malcolm's job "very difficult". Sir Malcolm, who was secretly filmed apparently offering his services to a company, says no Commons rules were broken. But in a BBC Newsnight interview last night, former Labour MP Mr Howells said the committee - which oversees the work of Britain's intelligence and security agencies - cannot afford to be "dragged down" by the row because it is "too important". Get the full story here.
It was a hectic day yesterday with the fallout from Channel 4 and the Daily Telegraph's undercover filming of Westminster heavyweights Jack Straw and Sir Malcolm Rifkind. They were accused of offering their services to a private - fictitious - company for cash. Both men deny wrongdoing but that didn't stop the political heavens from opening upon them - Sir Malcolm lost the Conservative whip and both men referred themselves to the parliamentary standards commissioner.
