Ukraine is set to be top of the agenda as Foreign Secretary James Cleverly begins a two-day trip to the US and Canada.
Speaking ahead of his departure, Mr Cleverly said: “The UK, US and Canada always have each other’s backs when it counts, protecting the rules-based order for nearly 80 years.”
He continued: “Today we stand united against Putin’s illegal war, and we will continue to use our uniquely strong defence and security ties to ensure that, in the end, the Ukrainian people will win.”
He will deliver a keynote speech at Washington’s Centre for Strategic and International Studies, at which he is set to outline Britain’s foreign policy priorities before talks with his US counterpart Secretary of State Antony Blinken. The two will then hold a joint news conference.
On Monday, Defence Secretary Ben Wallace announced that British tanks, artillery pieces and armoured vehicles are to be sent to Ukraine.
Mr Cleverly is set to use this British pledge to persuade the Americans and the Canadians to follow the UK’s lead. He is expected to stress the need for the right battlefield tools to be given to the Ukrainians quickly to allow them to win the war.
The Americans have delivered billions of dollars worth of weaponry to Ukraine over the past 11 months, but only in carefully managed tranches with limited capability for fear of provoking Russia.
Prime Minister Rishi Sunak has said he is committed to the acceleration of the UK’s diplomatic and military assistance to Ukraine as Russia prepares to launch a new offensive.
Top members of President Biden’s team are in the Ukrainian capital this week for meetings with President Zelenskyy.
Antony Blinken’s deputy Wendy Sherman, Dr. Colin Kahl, undersecretary of defence for policy and Jon Finer, principal deputy national security adviser, are all in Kyiv after meetings in Germany and Poland where they discussed continued US support for Ukraine.
Beyond Ukraine, the British government hopes the elusive UK-US trade deal will be discussed with the Americans in Washington.

In Toronto, on Wednesday, Mr Cleverly is set to discuss British efforts to become a member of the Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), a key free trade agreement between 11 countries including Canada.
Britain has reached the final phase of CPTPP accession, but disagreements remain over levels of market access the existing members would have to Britain.
Northern Ireland is also set to feature in discussions between Mr Cleverly and Mr Blinken. As speculation mounts that a EU-UK compromise over the Brexit Northern Ireland Protocol may be close, the UK will seek the support of the US.
President Biden has taken a close interest in negotiations over Northern Ireland and has made clear that the UK’s handling of the issue could impact the chances of a US-UK trade deal.
