The UK Government is being urged by the opposition to halt Brexit proceedings as a prominent ‘Leave’ campaigner has become subject of an investigation by the National Crime Agency.

It is alleged Mr Arron Banks, the man behind the Leave EU campaign, is not the true source of £8m in funding, as was disclosed to the electoral commission. 

In a statement from Downing Street, the Government said they would not make comment on the open investigation, however Labour MPs say Brexit must be put on hold until Britain knows the extent of “crimes against democracy”.
