Former Tower Hamlets mayor Lutfur Rahman says he will appeal a court ruling forcing him from office.
Last week a special election court ordered that Mr Rahman’s re-election in May 2014 be nullified after finding him guilty of electoral fraud.
The former mayor was also barred from standing in June’s re-run of the election.
Mr Rahman denies any wrongdoing and has now issued a statement confirming his attention to appeal the ruling and accusing the court of “bias, slurs and factual inaccuracies” in its judgement.
The statement also confirmed that Rahman’s Tower Hamlets First party will be fielding a candidate in June.
On Sunday the Labour party confirmed John Biggs, who lost to Rahman in last year’s contest, as their candidate in the new election.
