An evening optimistically billed as 'the greatest Labour fundraising event ever' will see former leader Ed Miliband leading a karaoke sing-a-long next month.

Miliband's only previous public singing of note was the annual rendition of The Red Flag that wraps up each Labour conference. And when he filled in for Jeremy Vine hosting the lunchtime show on Radio 2 last summer he tried his hand at a 'death metal scream' with limited success. But his turn at a Lewisham Labour fundraiser is described as a 'once in a lifetime event'.

There's no word yet on what the set list might include but his Desert Island Discs choices betrayed a taste for tunes that others might describe as 'cheesy'. He picked A-ha's Take on Me, Sweet Caroline by Neil Diamond and Angels by Robbie Williams on that occasion - all karaoke classics.

A slew of other MPs including Vicky Foxcroft and Ellie Reeves have signed up to attend the night out which is in support of Damian Egan's bid to become Mayor of Lewisham. However Miliband is the big draw, even if his previous party role is downplayed in literature for the event: he's described as a 'Twitter personality, podcast star, and former leader of the Labour party'.
