Sinn Féin is now the largest party in the council, the Assembly and Westminster in Northern Ireland.
The nationalist party, which did not take a seat in the House of Commons, has seven seats after Thursday’s UK general election – the same number as in 2019.
Its leader, Mary Lou McDonald, said it was time to “build a new future together on this island”.
The party came out on top after a disappointing night for the Democratic Unionist Party (DUP).
The DUP has eight seats in 2019 and returns in 2024 with five.
The top victim in Thursday’s vote was Ian Paisley, who lost their North Antrim seat his father first won in 1970.
In the Lagan Valley, Sorcha Eastwood of the Alliance Party took the seat held by former DUP leader Sir Jeffrey Donaldson since 1997.
Robin Swann of the Ulster Unionist Party (UUP) won South Antrim at the expense of the DUP’s Paul Girvan.
For Sinn Féin, there was a 4.2% increase in vote share compared to the general election five years ago.
The party also welcomes new faces, including Dáire Hughes and Cathal Mallaghan.
Former Royal College of Nursing leader Pat Cullen, a prominent figure in the British health strike, is returning to Sinn Féin in Fermanagh and South Tyrone.
Ms McDonald said Sinn Féin was “determined to build a constructive relationship with the new Labor government”.
He said his party expected the new prime minister “to uphold the Good Friday Agreement, helped by Labour, ensuring political, legal and constitutional guarantees are respected”.
DUP leader Gavin Robinson, who retained his seat in Belfast East, rejected suggestions that the election result strengthened the argument towards Irish unity, saying there was “no support for a border poll”.
Mr Robinson admitted the result was not what the party had hoped for and called for “greater cohesion” among unions.

There was a collapse of 250 seats for the Conservatives, with gains for the Liberal Democrats and UK Reform.
‘Critical issue’
Northern Ireland’s first minister and first deputy spoke to Sir Keir on Friday night.
First Minister Michelle O’Neill said: “We discussed a number of critical issues including the challenging budget situation.
“We insist that the UK government must put in place the right funding model to deliver the public services our citizens deserve.”
Deputy First Minister Emma Little-Pengelly said it was a “constructive discussion”.
“We also talked about the benefits of building a positive working relationship and strengthening the relationship between the NI Executive and the UK government going forward,” he said.

Ian Paisley losing his seat in North Antrim was a political earthquake that no one saw coming.
For 54 years, the seat was a family dynasty, synonymous with the Paisley name – and the entire DUP.
It was held by DUP founder Rev Ian Paisley from 1970 before his eponymous son succeeded him in 2010.
But it will now be TUV leader Jim Allister representing North Antrim in the House of Commons.
The alliance with Reform UK appears to be faltering after its leader Nigel Farage personally endorsed Paisley.
But the TUV’s objection to the DUP’s deal to restore Stormont seems to have been cut through, enabling Allister to overthrow the DUP’s majority in the party’s heartland.
For Allister, dismissed by the DUP as a “dead unionist”, this will be the sweetest of victories.
Who has been elected in Northern Ireland?
The first seismic results of the night came in Lagan Valley, where Sorcha Eastwood became the first woman in the constituency and the first non-unionist MP.
He defeated the DUP’s Jonathan Buckley, who contested the election instead of Sir Jeffrey, who has been charged with a history of sex offenses, which he denied.
Ms Eastwood said she was delighted with the victory, adding the party’s result was a “huge achievement”.
“I’m a Lagan Valley girl born and bred,” she added.
Mr Buckley said “boundary change” and “divided unionism” lost seats.
In North Antrim, in the main upset, the DUP’s Ian Paisley lost the North Antrim seat for Traditional Unionist Voice (TUV) leader Jim Allister, who described the result as “seismic”.
The TUV, which is aligned with Reform UK, has been highly critical of the DUP’s deal to bring the party back into the fold of governing in Northern Ireland.
The Social Democratic and Labor Party (SDLP) returned with two MPs, Colum Eastwood in Foyle and Claire Hanna in Belfast South and Mid Down.
‘Strategic planning’
Robin Swann’s victory in South Antrim means the UUP has its first MP since 2017.
He resigned as Stormont health minister for the race, which party leader Doug Beattie called “strategic planning”.
In North Down, there is a return to the independent unionist vote at Westminster.
Alex Easton, formerly of the DUP, defeated Alliance Party deputy leader Stephen Farry.
