As Ed Balls prepares to announce his intention to stand in the forthcoming Labour leadership election, Sunny Hundal is doing his bit to widen the field of would-be Labour leaders still further by encouraging MPs to sign John McDonnell's nomination papers.
Nominations close a week tomorrow and any candidate that wants to enter the race needs at least 33 signatories.
McDonnell has already complained that the brief nomination period disadvantages less established candidates while benefiting well-known faces such as the former foreign secretary David Miliband. "I think it undermines the democratic process from the outset," he told the BBC News Channel.
The blogosphere might now be McDonnell's salvation. Writing on his Liberal Conspiracy blog today, Hundal says he is convinced the "party needs a strong left-wing voice and John is the obvious candidate".
Hundal lists the MPs who backed McDonnell in May 2007 prior to Tony Blair's departure. (In the end, Gordon Brown was spared a leadership contest three years ago.) He also lists other members of the Socialist Campaign Group who didn't nominate him last time around, and encourages readers to "pick one or two names, find out their office numbers, call them and politely ask whether they would be nominating John McDonnell and why it's important that they do".
