Britain has distanced itself from a proposal by the French president for a one-month truce between Russia and Ukraine.

Emmanuel Macron said on Sunday that France and Britain were proposing a limited four-week ceasefire “in the air, at sea and on energy infrastructure”.

But Kyiv has raised reservations about any end to the fighting without security guarantees.

And on Monday one British official said there was no agreement on the truce plan.

“There are various options on the table, subject to further discussions with the US and European partners, but a one-month truce has not been agreed,” the official told the Financial Times.

On Sunday night, Mr Macron said that France and Britain were proposing a four-week truce in Ukraine “in the air, at sea and on energy infrastructure” but not, initially at least, covering ground fighting.

France insists a one-month truce between Russia and Ukraine would test Vladimir Putin’s “good faith” in wishing to “end this war”.

Speaking to France Inter radio on Monday, Jean-Noel Barrot, the French foreign minister, insisted that a one-month time frame “would allow to prove the good will of Vladimir Putin if he commits to a truce”.

“And it’s then that real peace negotiations would start. We want a solid peace and a durable peace,” he added.

An initial phase is “a way of verifying that Russia is willing to end this war”, said Mr Barrot, specifying that no withdrawal of Russian troops on the ground was envisaged during the truce.
