Karen Bradley, the Northern Ireland secretary, was challenged by British and Irish parliamentarians on the potential for violence if Brexit allowed any physical infrastructure to return to the Irish border. Senator Frank Feighan said that the people of Ireland would tear it down with their own hands, adding, ‘That’s what’s coming from the people on the ground, not from me’. In December 2017, both sides agreed to a ‘backstop’ position to avoid a hard border if a wider trade deal failed to be struck. Negotiators are now unable to translate this backstop decision into a legally binding commitment. Ms Bradley also expressed the opinion that if there were a second referendum, the vote to Leave would be even stronger.
