In pictures: First day back at Stormont

Northern Ireland's political parties are back at Stormont after Thursday's historic election.

There was a freshers' week feel on the hill but it does not look like they will be able to get down to business any time soon.

The Democratic Unionist Party (DUP) says it will not re-enter the Stormont power-sharing executive without "decisive action" from the UK Government on Brexit trading arrangements.
