Here's why Edwin Poots resigned as DUP leader after just 21 days - and who might replace him

Edwin Poots has resigned as leader of the Democratic Unionist Party (DUP) after just 21 days in the post.

Mr Poots was forced out on Thursday night (17 June) following a revolt within his party over a deal struck with Sinn Féin and the nomination of Paul Givan as Northern Ireland’s First Minister.

There are fears that the leadership meltdown in the country’s biggest party could threaten the future of power-sharing at Stormont.

So, why has Edwin Poots resigned from the DUP - and who might replace him?

Here is everything you need to know.

Why has Edwin Poots resigned from the DUP?

Arlene Foster, former leader of the DUP, formally stood down as First Minister on 14 June.

That meant both a new First Minister and Deputy First Minister had to be appointed within a week, unless a Stormont election would be called.

Before Sinn Féin agreed to nominate their own Deputy First Minister, the party demanded a commitment to put Irish language legislation in place.

Early on Thursday morning, a deal was reached, with Secretary of State for Northern Ireland Brandon Lewis declaring that legislation would be brought in by Westminster by October if not first introduced at Stormont.

The deal was designed to rectify a stalemate with Sinn Féin.
