Conservative MP Craig Mackinlay was questioned by Police under caution last week over his election expenses, the Telegraph can reveal.

The South Thanet MP reportedly spent six hours being interviewed by officers over alleged overspending in the 2015 election campaign in which he beat Nigel Farage and Al Murray, the Pub Landlord.

Kent Police are expected to meet with the Crown Prosecution Service next week to discuss a possible prosecution, it is understood, after the force concluded a series of interviews with Conservative staff and politicians about the alleged overspend.

Both Mr MacKinlay and his agent Nathan Gray have denied any wrongdoing.

The Electoral Commission opened an investigation into election spending in the constituency last year after a journalist at Channel 4 News made allegations about the spending on hotels for activists campaigning in the seat.
