Voters in Tower Hamlets must be vigilant and report anything they suspect as being electoral fraud, according to Crimestoppers and the Electoral Commission.

People are asked to report suspected cases of impersonation, intimidation and offers of bribery to vote for a particular party.

On polling day voters are also asked to look out for multiple people entering a booth.

Mark Hallas, chief executive of Crimestoppers, said: “Whilst electoral fraud is quite rare, it’s important for us all to be aware, lookout for it and work together to stop people from jeopardising our tradition of fair and free elections.”

In 2017 police forces across the UK investigated 336 allegations of electoral fraud.

Craig Westwood, Director of Communications and Research at the Electoral Commission, said: “Electoral fraud is a serious crime, and the cautions and convictions handed down in the last year show that the police take reports seriously.”

The local elections in 2014 ended in controversy after disgraced former mayor Lutfur Rahman was removed from office after he was found guilty of corrupt and illegal practices.
