iz Truss has completed her talks with world leaders and has met the King as she prepares to bid a final farewell to the Queen, along with hundreds of dignitaries from around the world.
The Prime Minister received her Irish counterpart on Sunday, as well as the Canadian Prime Minister and the Polish President in Downing Street.
She was supposed to meet US President Joe Biden, but the talks were called off on Saturday.
Instead, a “full bilateral meeting” is scheduled for Wednesday, when the pair will be in New York for the UN General Assembly.
Ms Truss also had an audience with Charles at Buckingham Palace on Sunday, ahead of his reception for visiting heads of state.
The weekend’s conversations with world leaders were framed by No. 10 as condolences on the Queen’s death, with politics likely to come up.
In particular, Mrs Truss’ meeting with Irish Prime Minister Michael Martin took place against a background of tensions over the future of the Northern Ireland Protocol.
Martin said he had a “warm” meeting with the British Prime Minister but declined to answer questions about the controversial post-Brexit treaty.
He left No 10 just under an hour after arriving on Sunday morning.
“I don’t think this is the time, if you don’t mind me saying it, to go into details on things like protocol,” he told the TNZT.
“I had a good phone call with the British Prime Minister last week, had a first warm meeting this morning where we discussed many issues in the context of the British-Irish relationship.
“But I do think that the opportunity is there for us to reset relationships and be aware of what we have achieved in previous years, the obstacles that have been overcome.
“And that gives us the strength to know that we have the capacity to overcome current obstacles, current problems that could potentially hinder the relationship, and I believe we can overcome them.”
Ms Truss also met Canadian Prime Minister Justin Trudeau and Polish President Andrzej Duda in Downing Street on Sunday.
The prime minister began talks with world leaders on Saturday and spoke with colleagues from New Zealand and Australia.
Meetings were held at the government’s residence in Chevening, rather than Chequers, which is reportedly undergoing routine maintenance work following Boris Johnson’s departure.
Sunday at 8pm, Ms Truss will observe a minute of silence with the country to mourn the death of the Queen and reflect on her life and legacy.
People are invited to celebrate the occasion in private at home, on their doorstep or on the street, or at community events and vigils.
