Donald Trump's reined back on his ability to end the conflict in Ukraine - following historic talks at the White House with Volodymyr Zelenskyy and European leaders.

The U.S. president's ruled out putting the country’s troops on the ground - while warning that Russia's Vladimir Putin 'might not want' to secure a peace deal.

The White House insists support from the air is both 'an option and possibility' as part of security guarantees.

White House Press Secretary Karoline Leavitt confirmed there are no plans to send American troops to enforce any future peace deal.

Meanwhile, the Kremlin has played down talk of an imminent summit between Vladimir Putin and Volodymyr Zelenskyy.

It comes after Donald Trump renewed his call for the two leaders to meet and discuss ways to achieve peace in Ukraine.

Russian officials have told the BBC they have not rejected the idea of direct talks, but say there shouldn't be "a meeting for the sake of a meeting".

To discuss this further, Alan Morrissey was joined by Donnacha O’Beacháin, Newmarket-on-Fergus native and Professor of Politics at Dublin City University.
