Taoiseach Leo Varadkar will pay an historic visit to the headquarters of the Orange Order when he travels to Belfast tomorrow.
The Fine Gael leader is also schedule to launch the Féile an Phobail's programme later in the afternoon.
It is believed the symbolic visit to Schomberg House in east Belfast will be the first time the head of the Dublin government has visited the Grand Orange Lodge of Ireland's headquarters.
Mr Varadkar is expected to meet Orange lodge members from the Republic as part of his visit.
His trip north comes at a time of tense relations between the taoiseach and unionist politicians over Brexit, with the latter accusing Mr Varadkar's government of aggressive tactics in negotiations over the shape of the border when the UK leaves the EU.
The Grand Orange Lodge of Ireland declined to comment on the anticipated visit when contacted by the Press Association.
Last year, Mr Varadkar attended a breakfast ahead of Belfast Pride.
Tomorrow afternoon he is scheduled to travel across Belfast to St Mary’s University College on the Falls Road, where he will launch the programme for this year's West Belfast Festival.
The community event, which is celebrating its 30th anniversary, runs from August 2 to August 12.
West Belfast MP Paul Maskey said: "An taoiseach’s participation in the launch will provide a huge boost to all those who work to make Féile the great success story it has become."
Meanwhile, Sinn Féin deputy leader Michelle O’Neill MLA has claimed the British government has no strategy for restoring the Stormont, while accusing Secretary of State Karen Bradley of being "disingenuous".
The Mid Ulster MLA said the north was fast becoming a "political and social backwater" due to what she characterised as the British government’s support for the "DUP’s anti-rights agenda".
"Comments by the British Secretary of State Karen Bradley that her priority is to re-establish the political institutions in the north are glib and disingenuous and there’s no evidence to support her assertion," Ms O'Neill said.
She said the Tory government had adopted a "do nothing approach" since the last negotiations broke down in February.
"Their inaction gives cover and tacit support support for the DUP’s shameful denial of rights, women’s rights, LGBT rights, language rights and the right of victims affected by the legacy of the past," the Sinn Féin deputy leader said.
The DUP yesterday hit back at claims by Sinn Féin MEP Martina Anderson that there were parallels between Arlene Foster's party and many far-right European groups.
Upper Bann MLA Jonathan Buckley said Ms Anderson's remarks were delivered to a "virtually empty" European Parliament chamber.
"When one considers the group in which Martina Anderson sits within the European Parliament, she should be careful labelling any party – her group comprises various shades of communism and those who voted against taking action against Isis," he said.
"For Martina Anderson it seems extremism is fine provided it's Sinn Féin’s brand of extremism that’s on offer."
