Dublin heaps pressure on May over Northern Ireland
Charles Grant, director of the think-tank the Centre for European Reform, said there was a nearly 50 per cent chance that Britain remains in a customs union with the EU indefinitely — in a move that would open up the possibility of a soft Irish border.
“If Labour as a bloc [at Westminster] decides that Britain should stay in a customs union, then there is no parliamentary majority for not being in a customs union,” he said.
