Northern Ireland's First Minister Michelle O'Neill has said the British government must deliver on its commitment to provide substantial funding to help rebuild Casement Park, the home of Antrim GAA, in west Belfast.
British Chancellor Rachel Reeves is due to announce a comprehensive spending review next Wednesday and it's viewed as a pivotal moment for the plan to redevelop the stadium.
The project has an estimated cost of £250m (€296.9m) and just under half is already in place, with the Irish government pledging around £43m (€51m), the Stormont Executive £62.5m (€74.2m) and the GAA £15m (€17.8m).
Ms O'Neill and her Sinn Féin colleague, north Belfast MP John Finucane, met the Northern Ireland Secretary of State in Belfast this morning.
Speaking afterwards, Ms O'Neill said she had stressed the "political significance" of the project going ahead as well as what she said would be huge economic benefits.
"This is something that's long overdue and I look forward to this day next week, whenever we actually see the outworkings of all of that, and will understand in more detail what it all looks like," she said.
"Casement Park must be built, that remains my position. It's an Executive flagship commitment, it still stands as an Executive flagship commitment so the British government must find a way to honour its political commitment, put their money on the table and actually back a project that will bring enormous benefits to everybody.
"The GAA is something to be celebrated , it's something that really celebrates diversity and something that really is at the heart of our community. This is a good thing, so let's now get on and get it done," she added.
Ulster GAA representatives meet MPs in Westminster
Representatives from Ulster GAA met with MPs in Westminster today to push for funding for Casement Park from the UK government.
Today's event was organised by Alliance MP for Lagan Valley, Sorcha Eastwood.
Speaking afterwards, she said: "GAA clubs are changing, they're diverse. We have people right across the community who play Gaelic Games and getting Casement Park built is a vote of confidence in a positive shared future".
Ulster GAA CEO Brian McAvoy said if sufficient money is allocated in next week's Spending Review, "we could be onsite towards the end of the year".
The President of Ulster GAA Michael Geoghegan spoke of the "massive economic benefits to the local community".
He also said that developing Casement Park would be significant in terms of the "importance of the GAA in every community, in every part of Ireland".
Sinn Féin Councillor and former Antrim captain Declan Lynch said he wanted future generations to have a chance to play at the stadium.
"I've had the opportunity to play at Casement Park, my wife's had the opportunity to play at Casement Park. We now have a young son. Both him and other young Gaels should have that opportunity also", he said.
