First Minister Paul Givan has confirmed his resignation, saying holding the post at Stormont has been the "privilege of my life'.
The move comes a day after his party colleague Edwin Poots’ decision to order a halt to agri-food checks at Northern Ireland’s ports.
DUP leader Sir Jeffrey Donaldson has repeatedly threatened to bring down the Stormont institutions in protest against the so-called Irish Sea border, introduced as part of the post- Brexit protocol.
