Edwin Poots has resigned as leader of DUP after just 21 days in the job.

It came after he agreed a deal with Sinn Fein and the Westminster government to ensure Paul Givan became Northern Ireland's first minister.

A majority of DUP members in the assembly wanted to delay the process and he faced an internal revolt at a party meeting.

What happened and what impact could this have on power sharing and Northern Ireland?
