PROSECUTORS are set to announce whether a string of Conservative MPs and officials will face charges in relation to allegations of breaching spending limits in the 2015 general election.

Some 14 police forces have sent files to the CPS - which are understood to refer to more than 30 individuals - and decisions on charges are due in late May and early June.

The list includes Avon and Somerset Police who said they could not name the MP concerned.

A Crown Prosecution Service spokesman told the Press Association that the announcement of the snap general election would have no impact on the timing of decisions on whether to press charges.

The precise deadlines for decisions vary from area to area, depending on the date last year on which the local force secured an extension to its investigations into alleged breaches of election finance laws.

Each file relates to allegations concerning a candidate and an election agent and the number of people involved totals at least 30, a CPS spokesman said.

Allegations highlighted by Channel 4 News and the Daily Mirror relate to busloads of Conservative activists sent to key seats, whose expenses were reported as part of national campaign spend rather than falling within the lower constituency limits.

The CPS declined to say which constituencies are involved, but said files had been received from the Metropolitan Police, as well as forces in Avon and Somerset, Cumbria, Derbyshire, Devon and Cornwall, Gloucestershire, Greater Manchester, Lincolnshire, Northamptonshire, Nottinghamshire, Staffordshire, West Mercia, the West Midlands and West Yorkshire.
