Foreign Secretary Liz Truss will meet officials in Washington to discuss further support for Ukraine after the UK and the US were thanked by Ukrainian President Volodymyr Zelensky for their moves to sanction Russian oil.
Ms Truss will meet US counterpart Antony Blinken and national security adviser Jake Sullivan to consider what more the two countries can do to support Ukraine on security, intelligence and humanitarian issues.
He earlier received standing ovations during a virtual speech to the House of Commons, during which he called for the UK to “make sure that our Ukrainian skies are safe”.
The historic address came shortly after ministers announced the UK will phase out the import of Russian oil and oil products by the end of the year.
In his daily address to Ukraine, Mr Zelensky went on to say: “This is a powerful signal to the whole world.
“Either Russia will respect international law and not wage wars, or it will have no money.”
Amid concerns over soaring energy costs, it was understood two Cuadrilla sites in Lancashire may be handed over to the Royal Geographical Society rather than being concreted over.
Fracking, or hydraulic fracturing, has been under a moratorium for more than two years but the move could allow the sites to be opened up at a later date.
US President Joe Biden ordered a ban on Russian oil imports, while the European Union was also expected to announce a phasing out of dependence on Moscow’s energy.
Business Secretary Kwasi Kwarteng urged businesses to “use this year to ensure a smooth transition so that consumers will not be affected”, with 8% of UK oil supply coming from Russia.
Transport Secretary Grant Shapps told airports he can order them to detain Russian aircraft and has the power to order the Civil Aviation Authority to terminate the registration of planes owned by sanctioned individuals.
The ownership of one plane at Farnborough Airport in Hampshire was understood to be under investigation.
A Government source told the PA news agency the aircraft “was transporting a wealthy Russian and the ownership of the aircraft is now the subject of an investigation”.
“The aircraft will only be allowed to leave Farnborough if the inquiry shows it is not a Russian-owned or controlled jet,” the source added.
“We will fight until the end, at sea, in the air. We will continue fighting for our land, whatever the cost,” the Ukrainian leader said.
“We will fight in the forest, in the fields, on the shores, in the streets.”
Meanwhile, fighting and evacuations continued in Ukraine, while the US rejected a surprise offer from Poland on Tuesday night to deliver Nato jets to the country with American help.
“It is simply not clear to us that there is a substantive rationale for it,” Pentagon spokesman John Kirby told the Associated Press.
The Ministry of Defence said its latest intelligence suggested Ukrainian cities were continuing to suffer heavy shelling but Vladimir Putin’s assault on capital Kyiv had failed to make major progress.
“The cities of Kharkiv, Chernihiv, Sumy and Mariupol remain encircled by Russian forces and continue to suffer heavy Russian shelling,” the MoD said.
“Ukrainian air defences appear to have enjoyed considerable success against Russia’s modern combat aircraft, probably preventing them achieving any degree of control of the air.”
