The British and Irish Governments have called on parties in Northern Ireland not to be distracted by calls for a General Election.
MP's are expected to back the Prime Ministers plan for a vote - when they meet in the commons later.

Politicians at Stormont meanwhile are set to resume crisis talks to restore power sharing here.
