Northern Ireland first minister resigns over Brexit checks on goods

Paul Givan's move triggers parallel departure of deputy first minister and could bring forward elections

The first minister of Northern Ireland, the Democratic Unionist party's Paul Givan, has resigned, plunging the devolved government at Stormont into turmoil two years after power-sharing with Sinn Fein was restored.

His resignation, over Brexit checks in the Irish Sea, will also bring the parallel departure of the Sinn Fein deputy first minister, Michelle O'Neill, under the power-sharing arrangements.
