Leave campaigners warn May against 'regulatory alignment' with EU

Gisela Stuart of Change Britain says move aimed at solving Irish border issue in Brexit talks would be 'completely unacceptable'

A pressure group linked to the former Vote Leave campaign has warned Theresa May that signing up to regulatory alignment with the EU to solve the Irish border problem will not allow Britain to "take back control" from Brussels.

Change Britain, which was launched last year with the backing of the foreign secretary, Boris Johnson, and the environment secretary, Michael Gove, made clear its belief that such a move would fail to respect the mandate of the referendum result.
