By the end of the 2010s, Sinn Féin was by far the strongest republican voice was rapidly building a stronger base in the Republic of Ireland where it had become the third largest party in the Dáil. But, the structures of the Peace Process and the Stormont Assembly meant that it was no further to significantly challenging of the political status quo in Northern Ireland. The vote for Brexit, based as it was on a binary notion of British sovereignty that had been fudged by the Good Friday Agreement, changed that. The nature of Britain’s exiting of the European Union had massive ramifications of the Irish border. With a majority of people in Northern Ireland voting to remain (with 85% of the nationalist population doing so), the unionist veto over the wishes of the wider population came under deeper scrutiny. For Sinn Féin, which had been a long-term critic of the EU, this provided an opportunity putting the border back on the agenda. For dissidents, they found themselves in the unlikely position of sharing the same political standpoint as Nigel Farage, Boris Johnson, Michael Gove, and, allegedly, the Queen.
