A by-election to replace Sinn Fein's Martin McGuinness as Mid Ulster MP will be held on 7 March.
Mr McGuinness, who is the deputy first minister of Northern Ireland, announced last year that he would resign as an MP
He formally left his seat on 2 January. Sinn Fein has pledged to end the practice of its representatives double jobbing in more than one elected body.

The party has an abstentionist policy, with all of its MPs refusing to attend Parliament.
