Polling stations have closed across Northern Ireland for the 2017 Assembly election.

The Electoral Office believe that turnout will be up on last year's figure which was 55%. Officials said their staff had been busy in all areas.

Two hundred and twenty-eight candidates are competing for 90 seats across 18 constituencies.

It is the second time the electorate had to choose a government in the space of 10 months.

The 2017 Assembly Election was called after the resignation of former Deputy First Minister Martin McGuinness.

This assembly election has seen one significant change from previous ones.

There will be a reduction in assembly members from 108 to 90.

Northern Ireland's 18 constituencies will return five MLAs each, not six as was the case beforehand.

The number of MLAs has been cut in order to reduce the cost of politics.

Forty-eight fewer candidates stood in this election than in May last year.

In Northern Ireland, the government must be run by Irish nationalists and unionists together.

When all of the 90 seats have been filled, the two biggest unionist and nationalist parties will get together to try to form a new government.
