Rejoining the EU would cost Britain £750m a week, a new Brexit campaign group has claimed.
Stay Out, a pressure group chaired by Oliver Lewis, the former deputy chief Brexit negotiator, claimed that Britain would need to pay £39.3bn each year in contributions if it returned to the bloc.
The group, which has received the support of Lord Gove, the former Vote Leave chairman, is the first to be formed since Andy Burnham opened the door to rejoining the EU.
