A member of Northern Ireland's DUP says he believes unionists 'would win' if a border poll took place there.
Sammy Wilson was speaking as Sinn Féin leader Mary Lou McDonald says she wants a vote within the next five years, following her party’s strong showing in the Stormont elections.
Sinn Féin has become the largest party in Northern Ireland for the first time, beating the DUP by two seats.
Mr Wilson told Newstalk Breakfast now is not the time to destabilise the region.
"There isn't the basis for a border poll - the border poll was only to be held when it was clear there was a significant demand for change.
"Sinn Féin and nationalists still do not have a majority of votes in Northern Ireland.
"And secondly I think that a border poll would be - I know that unionists would win it.
"70% of people in Northern Ireland say they would vote No in a border poll.
"But I think, as we've seen in Scotland, once you have one border poll then you introduce a destabilising impact on politics because people then move to the next one.
"And unlike Scotland, in Northern Ireland once you have one you've got to - by law - have another one in seven years' time.
"And I don't think that we need to have that kind of destabilisation at this particular time".
Mr Wilson, who is his party's Brexit spokesperson, also says they would campaign for the UK to leave the European Union again if the vote was tomorrow.
This is despite fallout from the Northern Ireland Protocol, which the DUP claims has weakened the region's link to Britain.
"If I had to campaign for Brexit tomorrow, we'd do it again.
"Don't forget: all the debate was it would stop the movement of people across the border between Northern Ireland and the Irish Republic.
"There was never, ever any mention of the movement of goods being impeded, or the need for a border for the movement of goods - never.
"The goods element was introduced afterwards when in the negotiations, both your own Government and the EU, decided that one way of keeping the United Kingdom in the Single Market and the Customs Union would be [to] introduce this idea that goods could not move across the border without having to have some checks".
