A group of rebel MPs have begun soliciting signatures for a round robin letter calling for Gordon Brown to step down, which they plan to hand to the prime minister after the results of the local and European elections have come in on Monday morning.
The Guardian has learned there are reports that the backbenchers think they can reach 70 or 80 signatories, with some claims that the letter could be delivered to Downing Street by the end of today.
Some backbenchers have seen the letter and are not signing it on account of a perception that the names already on the list are "too leftwing". The pair report that all this is being done by MPs sending a message to an email address. What should worry Brown about this is that it shows that the left are mobilising against him as well. Things are moving fast now.
