Tower Hamlets council said it was building on its "excellent electoral processes" as hundreds of police officers were guarding its polling stations today.
Officers are in place at every polling station in the east London borough, which has been rocked by an electoral fraud scandal.
Two weeks ago, the council election which took place last year was branded corrupt and illegal in a High Court judgment and disgraced mayor Lutfur Rahman thrown out of office. A re-vote has been ordered.
Some 346 police officers are on election duties in the borough today, with voters remarking on Twitter that they have never seen such a police presence before and saying it was "good to see after recent elections".
