Gloucestershire Police has confirmed that it is looking into an allegation it has received.
The force would not be drawn on which constituency or constituencies the allegation may refer to or even which party.

The investigation comes amid claims that the Conservative Party may have breached election spending rules in the run up to polling day last year.
The party faces allegations that accommodation costs of activists bussed into key constituencies around the country should have been recorded under individual candidates' limits, rather than as part of the national campaign.
The probe launched by Gloucestershire Police comes after the Electoral Commission met with police and prosecutors on Wednesday in a bid to ensure they do not run out of time to launch possible criminal investigations into Tory funding of the 2015 general election campaign.

The Commission believes its ongoing probe into alleged breaches of reporting obligations will take at least another month - taking it past the one-year time limit for launching criminal proceedings.
A Gloucestershire Police spokeswoman said: "We have received an allegation of electoral fraud and an investigation has been launched.
"We are considering an application for extension on time to investigate.
"This is in relation to the 2015 general election."
