The £350m NHS figure sued by the Vote Leave campaign was highly cited a being incorrect Getty

The Crown Prosecution Service (CPS) is considering whether the Vote Leave campaigns broke electoral law in the run up to the EU Referendum vote. A complaint of "undue influence" was formally made by a group spearheaded by Prof bob Watt (who does not use a capital letter on his first name), an expert in electoral law from the University of Buckingham.

The complaint centres on the much criticised and disputed claim that if Britain left the EU it would be able to take £350m ($434m) a week the government gave to the EU and spend it on the NHS.

Watt said this was just one example of Leave campaign groups making "assertions of fact that were knowingly misleading" in order to appeal for voters. One of the key Leave campaigners, Nigel Farage, even admitted "I think they made mistake in doing that" –when discussing the £350m promise on the morning of Britain voting to leave the EU.

Other examples including falsely stating Turkey is about to join the EU and "the UK has no border controls whilst in the EU" when billions are spent on the UK Border Agency, reported the Guardian.

Although a police complaint is usually needed to spark an investigation by the CPS, director of public prosecutions Alison Saunders can consider cases of alleged election offences if they are made directly to her office under the 1983 Representation of the People Act.

The complaint will be dealt with by a special crime team who deal with election offences.

A CPS spokesperson said: "We can confirm that this letter has been received and we are currently considering its content."
