BBC News - Gordon Brown 'stepping down as Labour leader'
• Gordon Brown has announced that he is going to resign. He said that he did not want to go immediately, but he said that he wanted Labour to have a new leader by the time of the party's autumn conference (ie by September). He accepted that he had to take responsibility for the party's poor election result. His resignation will make it easier for Labour to form a government with the Lib Dems. But he has now made it clear that he is going whether or not Labour remains in office.
• Nick Clegg has formally opened negotiations with Labour. This afternoon it became clear that Lib Dem MPs had reservations about the proposed deal with the Tories. Now Gordon Brown has slapped a counter-offer on the table. The Lib Dems could join Labour (and, Brown implied, the Scottish and Welsh nationalists and others) to form a "progressive" alliance. They would just about have a majority.
• Labour are planning to offer the Lib Dems a bill on bringing in the AV electoral system and a referendum on a fuller system of proportional representation. The Tories, by contrast, are offering a referendum on AV and fixed-term parliaments.
• The Labour leadership contest is now officially open. David Miliband is the clear favourite. Ed Balls will certainly be a candidate, and Ed Miliband has not denied reports that he may stand against his brother. Andy Burnham is also seen as someone with an outside chance of winning. There has been speculation about Alistair Darling, Alan Johnson and Harriet Harman replacing Brown, but all three have in the past signalled that they don't want the job.
