Northern Ireland’s political parties are set to resume talks to restore Stormont.
It follows the result of the general election, which saw the Conservatives returned with a large majority.
Writing on social media on Sunday, Northern Ireland Secretary Julian Smith said he had spoken on the phone with all of the party leaders.
Mr Smith said he was looking forward to starting a “positive process” to get Stormont back up and running.
The talks follow a pledge from the UK and Irish governments to restore the executive.
Discussions on Monday will be separate meetings between Mr Smith and representatives from the various parties, with round table talks set to happen later in the week.
Stormont has been inactive since January 2017, when the DUP and Sinn Féin split in a bitter row.
Democratic Unionist Party (DUP) leader Arlene Foster said a desire for the restoration of Stormont was “the clear message of the election”.
“Central to the talks must be the sustainability of the institutions so never again can one party hold the rest of Northern Ireland to ransom,” she said.
“Northern Ireland can only move forward when we are prepared to work together,” she added.
Ulster Unionist Party (UUP) leader Steve Aiken called for reforms to be made, and said the “core issues which undermined devolution previously” must be addressed.
Sinn Féin’s vice president, Michelle O’Neill, said she wanted to see the political institutions “restored on a credible and sustainable basis”.
“All parties should commit to being round that table, providing political leadership and setting out our own agenda and priorities,” she said.

With the DUP and Sinn Féin both suffering some bruising defeats in Thursday’s election, the focus has shifted back to Stormont.
Julian Smith has kept his role in Boris Johnson’s cabinet as the Northern Ireland secretary, insisting talks must reach a breakthrough before the 13 January, or he will be legally required to call a fresh assembly election.
It seems unlikely the two biggest parties would relish another election so soon – but, we have been here before.
There are still hurdles to overcome, if a deal is to be brokered quickly.
Alliance party leader and MEP Naomi Long said her party would be playing a “constructive role” in restoring the institutions.
“If there is no successful resolution, the secretary of state must call fresh elections and then it is over to the public to elect those who want to get on with the job of delivering for everyone,” she said.
SDLP Leader Colum Eastwood said the parties must set aside their differences to restore power sharing institutions at Stormont.
He said: “We are entering last-chance talks this week. The SDLP has made bold proposals that are uncomfortable for us but are in the interests of restoring government to meet the needs of patients, pupils and healthcare workers.”
The legal date for an assembly election to be called if no power-sharing government is formed at Stormont is 13 January.
During a phone call on Friday evening, Mr Johnson and Taoiseach (Irish Prime Minister) Leo Varadkar said they would work closely with the Northern Ireland parties to help bring back devolution.
They also agreed on the importance of a close relationship between the UK and Ireland.
Mr Johnson updated the taoiseach on the timings for the reintroduction of the Withdrawal Agreement Bill next week and its passage through Parliament to ensure the UK leaves the EU on 31 January.
The prime minister made clear in the phone call his top priority was the restoration of a functioning executive as soon as possible.
He said Northern Ireland Secretary Julian Smith would dedicate himself to the talks process.
