Lutfur Rahman, has won the Tower Hamlets LBC mayoralty six years after an electoral commissioner removed him from office.
Mr Rahman, who formed the Aspire party following his eviction from the post, secured 39,533 first preference votes – nearly 12,000 more than the Labour incumbent John Biggs. With the other five candidates dropping out, second preference votes pushed him comfortably over the 50% threshold required.
In 2015 he was banned from standing for office for five years after a civil court found him guilty of corrupt and illegal practices. Richard Mawrey, the election commissioner who ousted Mr Rahman from office in 2015, said he had "driven a coach and horses through election law and didn't care".
The Electoral Commission upheld a number of allegations against Rahman and his former party, Tower Hamlets First, around the 2014 election.
Mr Rahman continues to deny any wrongdoing.
