Prime Minister Liz Truss will meet Joe Biden and Emmanuel Macron in New York against the backdrop of Brexit tensions and questions over whether she regards the French leader a “friend or foe”.
In her first foreign trip as Prime Minister, Truss was flying overnight to the States for the annual United Nations General Assembly (Unga).
The visit will contain a series of meetings, including with the EU’s Ursula von der Leyen, and a speech to world leaders. It comes as political action resumes after the period of national mourning for the Queen.
Truss hopes the focus will be largely on energy security and combating Russia’s war in Ukraine, but clashes over the Northern Ireland Protocol are bound to feature.
Biden, the US President, has raised concerns about Brexit’s threat to the peace process and has downplayed the chances of striking a free-trade deal.
His French counterpart, Macron, has long been a critic of Brexit and has been firm in pressing the UK to keep to commitments on Northern Ireland and fishing rights.
Truss sparked a diplomatic row during the Tory leadership contest when she declined to give a clear answer when asked if the president of the allied nation was a “friend or foe”.
Instead, the then-foreign secretary said last month that the “jury’s out”.
Ahead of the visit the Prime Minister’s spokesman described France as a “longstanding ally” and insisted relations between London and Paris, as well as with the EU, are “good”.
Asked if the meeting with Macron will be uncomfortable, the spokesman said: “No, the Prime Minister wants to build a constructive relationship with President Macron.”
But the spokesman maintained the position on the controversial Northern Ireland Protocol Bill, which the EU and others say will break international law.
Truss will meet Macron and Von der Leyen on Tuesday, before seeing Biden on Wednesday. She had been set to talk to the US President in Britain over the weekend as he visited for the Queen’s funeral, but the meeting was postponed.
She is not scheduled to receive the White House visit that Boris Johnson was treated to during his visit to Unga last year.
Meetings with Turkey’s Recep Tayyip Erdogan, Spain’s Pedro Sanchez and Israel’s Yair Lapid are also scheduled, and Truss will warn that now is not the time to “take our foot off the gas” in opposing Vladimir Putin’s invasion of Ukraine.
“We will continue to act to restore sovereignty and self-determination to Ukraine because this isn’t just Ukraine’s fight, the whole world suffers when a regime like Putin’s is allowed to bully and blackmail its neighbours,” her spokesman said.
She will seek to use the visit to “spur further international action to end energy dependence on Russia making sure the world is never in this position again”.
“In the short term that means increasing the supply of gas and other sources of energy and in the long term it means democracies tapping into our shared resources, natural, technological and entrepreneurial to develop alternative sources of energy.”
Before leaving the States on Wednesday evening, Truss will use her summit speech to say the UK under her leadership will be “an active defender of our democratic values” and will work to counter authoritarianism with allies.
The trip kicks off a frantic few days of political action in Truss’s fledgling premiership, with details on how businesses will be helped through the energy crisis and a major announcement on the NHS billed.
Truss, who was being joined by Foreign Secretary James Cleverly in the US, will then return ahead of Chancellor Kwasi Kwarteng’s mini-budget on Friday.
Labour urged the Prime Minister to use the trip to start “rebuilding our country’s diplomatic influence”.
Shadow foreign secretary David Lammy, who was also attending Unga, said: “12 years of Conservative governments making diplomatic gaffes, announcing plans to break international law, failing to live up to promises on climate action and cutting international aid have damaged relations with the US and left Britain isolated on the global stage.
“After being snubbed by the Biden administration within her first weeks in office, Liz Truss urgently needs to wake up to the damage her reckless approach to foreign policy is doing to the UK’s national interest.
“The Prime Minister must use the UN General Assembly to bring the UK back in from the cold and begin rebuilding our country’s diplomatic influence.”
Cleverly will call for action on Russian barbarity in Ukraine in a series of meetings with his counterparts, including US secretary of state Antony Blinken and Ukrainian foreign minister Dmytro Kuleba.
He will take part in a foreign minister-level UN Security Council meeting focused on the Russian invasion on Thursday.
