Foreign secretary David Cameron is giving evidence to MPs and members of the Commons European scrutiny over the planned treaty for Gibraltar.
Both governments are currently in the process of agreeing a post-Brexit treaty amid fears Gibraltar could become subject to Schengen area rules.
MPs warned the Brexiteer that his promise of a stronger sovereignty has failed and it could lead to a loss of control of British territories.
They are concerned Lord Cameron’s draft would leave UK citizens at the mercy of EU Frontex border guards and give them the power to turn away people from the territory.
During today’s Commons session, MPs are demanding answers to a list of key questions following evidence sessions with foreign minister David Rutley and Gibraltar’s chief minister Fabian Picardo.
It comes as National Audit Office warned the Government is splashing £4.7bn in Brexit border checks system. The watchdog also found there is no clear timetable to fully implement its post-Brexit border controls.
Sir Jim Ratcliffe has joined criticism and has slammed the Conservative Government for the way post-Brexit policies were handled, saying it didn’t turn out as people anticipated.
