'Clean Brexit' could save UK £450m a week, claims pro-leave group

Change Britain says UK could save 24bn a year by leaving single market, customs union and 'burdensome regulations'

A pressure group backed by a string of former Vote Leave campaigners from Michael Gove to Gisela Stuart has claimed that exiting the EU with a "clean Brexit" could save the country 450m a week.

During the referendum campaign, Vote Leave controversially argued that leaving the EU would leave an extra 350m a week to spend on the NHS.
