The nationalist pro-Irish Irish party Sinn Fein says the installing of a nationalist first minister in North Ireland, after the main pro-UK party agreed to endorse a deal with London, will be "a moment of very great significance". Speaking in Belfast, Sinn Fein president Mary Lou McDonald says it will mark "the extent of change that has occurred here in the north and indeed right across Ireland". The The Democratic Unionist Party (DUP agreement with London -- approved on January 30 in an internal vote at a closed-door meeting in Lisburn, near Belfast -- formed a basis to restore the Northern Ireland Assembly, that has been paralysed for nearly two years.
