Theresa May is considering making changes to the agreement which brought peace to Northern Ireland in order to persuade lawmakers to support her Brexit deal, The Telegraph reports. The Good Friday Agreement, signed in 1998, effectively brought an end to the Troubles which plagued Northern Ireland for decades. May needs to find a way to win more support for her Brexit deal after it suffered the worst defeat in British parliamentary history. Many lawmakers rejected the deal because of the so-called Irish backstop which would create a customs union between the U.K. and the EU in order to prevent a hard border between Northern Ireland and the Republic. May reportedly wants London and Dublin to add words to the Good Friday Agreement which would guarantee an open border, which May believes could be enough to remove the backstop from her deal. May's suggestion comes two days after a bomb was let off in Northern Ireland's Derry which police believe may have been the work of the New IRA.
