Northern Ireland’s political leaders have cast their ballots in the Assembly election.
The process is taking place amid speculation of a potentially seismic result, with Sinn Fein hoping to emerge as the largest party for the first time.
The party’s vice-president Michelle O’Neill filled out her ballot paper in St Patrick’s primary school in her home village of Clonoe, Co Tyrone, accompanied by party colleague Linda Dillon.
She posed for photographs with some voters before leaving.
Thirty miles away, DUP leader Sir Jeffrey Donaldson cast his vote at Dromore Central primary school in Co Down.
He is hoping that his unionist party will retain its position as the largest at Stormont.
He repeated his message that the UK Government needs to act over the Northern Ireland Protocol.
He said: “I think people are determined to see unionism winning in this election.
Unionist rival Doug Beattie, leader of the Ulster Unionist Party, voted at Seagoe primary school in Portadown, Co Armagh.
He said: “It’s polling day, I don’t think anybody really knows the outcome of this. Things change throughout the day. We are still canvassing.”
Naomi Long, leader of the cross-community Alliance Party, cast her ballot accompanied by husband Michael at St Colmcille’s parochial house in the east Belfast constituency where she was once the MP.
Colum Eastwood, leader of the nationalist SDLP, voted at the Model primary school in his home city of Londonderry accompanied by his wife Rachael and his children.
He said: “The people are all powerful today and the people will cast their vote. We are very confident we will do well.”
Jim Allister, leader of the TUV, voted early in the morning at Kells and Connor primary school in Co Antrim.
The DUP and Sinn Fein are vying for the top spot in the election, which comes with the entitlement to nominate the next first minister.
A unionist party has always been the biggest in the Assembly, and previously the Stormont Parliament, since the formation of the state in 1921.
This year a number of opinion polls have suggested that Sinn Fein will finish ahead of the DUP to become the first nationalist or republican party to emerge top.
While the office of the first and deputy first minister is an equal one with joint power, the allocation of the titles is regarded as symbolically important.
A surge for the centre-ground Alliance Party has also been suggested in pre-election polls.
The Northern Ireland Protocol has cast a long shadow over the election campaign following the resignation of First Minister Paul Givan in February in an effort to force the UK government to act over the post-Brexit trading arrangements.
This action left the Executive unable to fully function.
While ministers remained in post, they were restricted in the actions they could take.
Unionists object to the additional checks on goods arriving in Northern Ireland from Great Britain as a border in the Irish Sea.
Secretary of State Brandon Lewis urged the public to vote.
He also revealed he has told the parties of the need for them to work together to restore fully functioning devolved government after the election.
“The people of Northern Ireland are going to the polls today. I encourage everyone to get out there and cast their vote.
“It is vital that we give people the space to vote in an atmosphere of tolerance and respect,” he said.
“I have conveyed to the parties the need for them to work together to restore fully functioning devolved institutions as soon as they can, when the count is complete.”
Five Assembly seats are up for grabs in 18 constituencies, with the overall number of MLAs returned 90.
A total of 239 candidates are running.
Northern Ireland uses the single transferable vote (STV) proportional representation electoral system.
Counting will start at three centres in Belfast, Jordanstown and Magherafelt on Friday morning with the first results expected later in the day.
The DUP won 28 seats at the last Assembly elections in 2017, just ahead of Sinn Fein which returned 27 MLAs.
Next was the SDLP with 12 seats, the Ulster Unionist Party with 10 seats, Alliance with eight seats, the Green Party with two seats while People Before Profit and the TUV had one MLA each.
This year the DUP has been regarded as playing it safe, running 30 candidates, while Sinn Fein is running 34.
Meanwhile the UUP is running 27 candidates, the Alliance Party is running 24, the SDLP is fielding 22, TUV is putting up 19 candidates, the Green Party is running 18 and People Before Profit 12, as is Aontu, while the Workers Party is running six candidates and the PUP three.
The Irish Republican Socialist Party (IRSP) and the Socialist Party are each fielding two candidates, while the Northern Ireland Conservatives, Cross Community Labour Alliance (CCLA), Resume NI and Heritage Party are each running one candidate.
There are 24 independent candidates.
Polling stations close at 10pm.
Chief electoral officer Virginia McVea has advised voters to wear masks to prevent the potential spread of Covid-19.
