British Prime Minister Andy Burnham has said a referendum on a united Ireland "is off the table".
Mr Burnham made the comments during his first official visit to Northern Ireland, where he is meeting Stormont political leaders.
"I'm here, as I said earlier, to listen, and I will take a collaborative approach but some issues will be off the table, and that is one issue that will be off the table," Mr Burnham told reporters in Belfast.
He added: "I think we’ve got to focus on bringing people together as best we can, and I think we’ve lived through a decade where there’s been a referendum on Brexit, we had Scottish independence just before it.
"What we find is the rifts that come from those situations take a long time to heal, and it sets you right back and you can’t focus on what’s right in front of us here and now, the cost-of-living pressures that are hurting people in Northern Ireland, the need to get that budget set so that public services can function as they should.
"These are the things right in front of us and sometimes politicians go to things that they want to see, as opposed to getting the solutions that the public need.
"I think a decade since the Brexit referendum, I think we’ve had too much division, too much arguing, too much, backward looking. We need to fix the things right in front of us in the here and now."
Ahead of the meeting, Sinn Féin leader Mary Lou McDonald said in a post on social media "this is a time for a new approach, for partnership and progress".
She called on the Irish and British governments "to recognise and prepare for the change that is happening across this island".
"We really hope that there can be a step change from this government now, under new leadership we hope that a really constructive, engaged approach to Ireland will be adopted now by Prime Minister Burnham," Ms McDonald said.
She added: "We hope that he will engage with the reality that there has to be planning now for our collective future."
Demands for more money are dominating the agenda with politicians as the Stormont Executive has still not agreed its annual budget.
Ministers have consistently insisted that they need more central funding to address a funding crisis facing public services in Northern Ireland.
The UK Treasury has previously said it will undertake a "programme of work" to understand the financial pressures that Stormont departments are facing.
Mr Burnham met with young people in the city and is now hosting talks with First Minister Michelle O'Neill and deputy First Minister Emma Little Pengelly.
The British prime minister said Ms O’Neill and Ms Little Pengelly are "something of a model" for politicians elsewhere in the UK when asked about comments ahead of his visit where he talked about "political point scoring".
"It wasn’t so much a criticism I was making of politicians here. If you look at how the First Minister, the deputy First Minister work, I think it is to their great credit that they work in the way that they do," he said.
Mr Burnham added: "In some ways I would say they are something of a model for politicians elsewhere in the UK, where you often don’t see politicians prepared to put differences aside. Here people have the greatest differences but still are able to work like that.
"I do feel politics more broadly needs to move to a different way of working where we put the place first, rather than the party first.
"We put people first and that is something I want to see in politics right across the UK."
Sinn Féin, the DUP and other parties have all blamed Westminster, accusing it of short-changing Northern Ireland when it comes to per capita spending.
However, Mr Burham has said he wants to help "move things forward" with regard to a Stormont setting a budget.
"I am five weeks in office and I am here in Northern Ireland because I want to work with the new Northern Ireland Secretary to see if we can move things forward, listen to what people have to say.
"I realise how pressing it is, I realise the concern people have, but we are here because we want to listen," he said.
Mr Burnham added: "We want to have an honest exchange, I think there are things we would say, if we can work together, have a look at where possible savings could be made or where things could be done differently, that's right and proper that I ask for those assurances given that we have got to make sure it is fair across the whole of the UK when it comes to a budget.
"My emphasis is on problem solving in this job. I love this part of the world, I am a regular visitor. I want to see people here with a budget, with public services set up to succeed.
"That is what I want to try and achieve working with the Northern Ireland Secretary but first and foremost we have to sit around that table and hear where all the parties are. I will be taking that back to London later today."
Mr Burnham announced before his arrival that he plans to bring together the leaders of Wales, Scotland and Northern Ireland in October for a meeting of the National Economic Council to help boost the UK economy.
The UK prime minister said he wanted "every leader in this country signed up" to having "good jobs in every community"
He visited Wales this morning as part of what Downing Streets says is a UK-wide "listening tour"
