Tower Hamlets campaigner Andy Erlam will stand for London Mayor.
The man who led the legal battle to remove Lutfur Rahman, the former mayor of the borough, from his post has thrown his hat into the ring on behalf of the Red Flag Anti Corruption Party.
He will seek to replace Boris Johnson in the May 2016 election.
Rahman was removed from his east London post in April after he was convicted of electoral fraud.
Erlam then mounted an unsuccessful campaign to replace him, one which was won by labour’s John Biggs.
Running for London mayor he told the BBC he was intent on putting a stop to “Met police corruption.”
He will face competition from Conservative Zac Goldsmith, Labour’s Sadiq Khan, the Greens’ Sian Berry, Liberal Democrat Caroline Pidgeon, UKIP’s Peter Whittle and Respect’s George Galloway.
Former civil servant Siobhan Benita and housing campaigner Lindsey Garrett have also put their names forward.
