Conservative party has been fined £70,000 for breaking election rules.
The police are now investigating the case.
The party broke spending rules by moving its staff and campaigners from its headquarter to boost local party efforts and not properly declaring bills.
Labour and Liberal Democrats have previously been fined for breaking election rules.
“Seventy thousand pounds is a lot of money, but in the context of a political campaign where millions of pounds are spent, it’s not exactly going to break the Tories’ bank. But the political cost of what might happen next is much higher,” said the political editor for the BBC.
Thirteen police forces are examining this case.
