British Prime Minister Keir Starmer welcomed a breakthrough in relations between Kyiv and Washington, SkyNews reported on Tuesday.

Ukraine has agreed to a 30-day ceasefire proposal and the US says it will restart military aid and intelligence-sharing with Kyiv after a big day of peace talks in Saudi Arabia.

Hailing a "remarkable breakthrough", the PM congratulated Trump and Zelenskyy and said it was an "important moment for peace in Ukraine".

"We now all need to redouble our efforts to get to a lasting and secure peace as soon as possible,” the SkyNews quoted the PM as saying.

Starmer will be hosting virtual talks with potential members of a peacekeeping coalition on Saturday.
