COLCHESTER MP Will Quince is facing a police investigation into allegations he did not declare all of his electoral spending during last year’s General Election.

It is understood the investigation is the result of a complaint of electoral fraud made to Essex Police by a constituent.

The complainant is not being named, but political insiders are suggesting it was a local council politician in a different party.

It is claimed although Tory Mr Quince’s final spending was within £482.49 of the limit, that sum did not include the costs of party activists’ train travel to Colchester from London on the day David Cameron visited the town.

Mr Quince’s final accounts stated he spent £0 on transport.

The PM had a tour of Colchester business Fläkt Woods alongside Mr Quince on April 24 last year (pictured).

Earlier in the day, the Colchester candidate toured the town centre alongside Sol Campbell and other Tory activists.

But yesterday Mr Quince insisted he had nothing to hide.

He said: “I cannot comment on an active police investigation, which I plan to comply fully with.

"Local election expenditure was declared in accordance with the law.”

He added: “I won’t let this distract me from the important work I am doing on behalf of the people of Colchester as their MP.”

Mr Quince also said stops on national tours, such as when Mr Cameron was in Colchester, are considered national expenditure.

Former Colchester MP Sir Bob Russell, who lost the seat to Mr Quince by 5,757 votes in the election, said: “As this is being investigated by the police, I think it would be prudent not to comment at length.”

If convicted, the maximum punishment for electoral fraud is one year in jail or an unlimited fine.

An Essex Police spokesman said: “We have received allegations of potential electoral fraud and are currently reviewing the material provided to us to establish if there are any offences.

"Essex Police has been granted an extension of 12 months to investigate this allegation.”

Separately, the Conservative Party is also facing questions over a wrap around which appeared in this newspaper one week before the May 7 election.

It did not mention Mr Quince by name and appeared in publications in other perceived marginal parliamentary seats.

A Conservative Party spokesperson said: “Spending on wraparounds was correctly declared.”
