Boris Johnson has met with senior DUP figures in Northern Ireland overnight in an effort to continue the deal keeping his government in power.
The Conservatives hold a slim majority in Parliament thanks to the support of the DUP, but this could be further cut should the Liberal Democrats win a by-election in Brecon & Radnorshire later this week.
In return for DUP support the government has spent £1 billion in Northern Ireland since the 2017 election.
DUP leader Arlene Foster was among those meeting the new Prime Minister, and said she was “delighted” for the visit so early in his premiership.
“We want to see devolution restored in Northern Ireland, Brexit delivered and the union strengthened,” she said.
Mr Johnson will today meet the five main parties in Northern Ireland’s parliament to discuss the powersharing impasse that has lasted two-and-a-half-years.
Northern Ireland has been without a devolved government during this time as the DUP and Sinn Fein remain at loggerheads.
Mr Johnson said the region had been without proper governance “for much, much too long” and he will do everything in his power to help the parties reach agreement.
“Northern Ireland's citizens need and deserve the executive to get up and running again as soon as possible, so that locally accountable politicians can take decisions on the issues that really matter to local people,” he said.
Mr Johnson has visited regional England, Scotland, Wales and Northern Ireland in the past few days.
