The Crown Prosecution Service (CPS) has announced it will not charge any Tory politicians over the alleged breeching of expenses rules during the 2015 election campaign.

CPS investigators examined files from 14 English police forces and concluded that no further action would be taken.

An examination into the party’s campaign in Kent has not finished and a decision will be announced later.

Nick Vamos, head of special crime at the CPS, said: "We considered whether candidates and election agents working in constituencies that were visited by the party's 'battle bus' may have committed a criminal offence by not declaring related expenditure on their local returns.

“Instead, as the Electoral Commission (EC) found in its report, these costs were recorded as national expenditure by the party.

“To bring a charge, it must be proved that a suspect knew the return was inaccurate and acted dishonestly in signing the declaration.

“Although there is evidence to suggest the returns may have been inaccurate, there is insufficient evidence to prove to the criminal standard that any candidate or agent was dishonest.”

An examination into the party’s campaign in Kent has not finished and a decision will be announced later.

The EC fined the Tories £70,000 and found the party had failed to declare more than £275,000 in expenses relating to its ‘battle bus’ strategy.

A battle bus visited Mr Scully’s team on May 7, 2015, the day of the election.

In March this year Mr Scully, who unseated Liberal Democrat Paul Burstow, said he had done nothing wrong and had co-operated with the police investigation.

Today Mr Scully told the Sutton Guardian he was ‘relieved the issue was finally resolved’.

He added: “I think the findings prove what I have been saying all along that I did nothing wrong. The police had to spend a lot of time addressing politically motivated complaints that were made against us.

“I just want to carry on with the job and get out and speak to people ahead of the election.”
