There are various reports on the internet on the one-hand citing that Sinn Fein taking potential seats in Parliament to block the Tory / DUP Alliance is likely to happen and conversely that Sinn Fein have stated that this is not their intention:
Sinn Fein have dismissed speculation they would take their seats in Westminster to help Labour block Theresa May’s Queen’s Speech.
The Irish republican party visited London to hold meetings with ministers and to set up their parliamentary office but the party maintained its traditional refusal to take its seats out of opposition to Westminster’s jurisdiction in Northern Ireland and the oath all MPs must make to the Queen.
Paul Maskey, Belfast West MP, told a media briefing in Westminster: “Almost 250,000 people voted for us, for the seven of us and others who were unsuccessful, they gave us that mandate not to take our seats.
Theresa May will hold talks with Sinn Fein, the Ulster Unionists, the SDLP and the Alliance Party today in an attempt to allay concerns about the Conservative-DUP deal.
Sinn Fein and other nationalist parties have warned that the Government risks its impartiality in Northern Ireland if it strikes an agreement with the DUP, a unionist party.
Many, including former Conservative Prime Minister John Major, have warned that a deal could threaten peace in Northern Ireland.
Sinn Fein’s Stormont leader Michelle O’Neill said: “I will be making it very clear that any deal between the Tories and the DUP cannot be allowed to undermine the Good Friday and subsequent agreements.
