Donald Trump has said he believes Vladimir Putin is ready to make a deal on the war in Ukraine as the two leaders prepare for their summit in Alaska on Friday, but his suggestion the Russian leader and Volodymyr Zelenskyy could “divvy things up” may alarm some in Kyiv.

The US president implied there was a 75% chance of the Alaska meeting succeeding, and that the threat of economic sanctions may have made Putin more willing to seek an end to the war.

Trump insisted that he would not let Putin get the better of him in Friday’s meeting, telling reporters: “I am president, and he’s not going to mess around with me.

“I’ll know within the first two minutes, three minutes, four minutes or five minutes … whether or not we’re going to have a good meeting or a bad meeting.
