The war in Ukraine needs "concessions on both sides" if it is to come to an end, Nigel Farage has said.
The Reform UK leader suggested the invaded nation could gain "quite a lot from settling", though he refused to say if this meant giving up territory to Russia in return.

Mr Farage was speaking to Sky News after travelling back from America following his ally Donald Trump's election victory.
Asked about the president-elect's claims he could end the war in Ukraine "on day one", Mr Farage said: "Well, the war is horrendous. There are nearly a million battle casualties. It's like the battle of the Somme with drones.
"We have two options. We can keep feeding Ukraine, and that's fine. And the war goes on for another year, two years, five years. The casualties mount. What Trump has said is he wants to attempt to broker a peace deal."
The Clacton MP said that would require "concessions on both sides", adding: " I think Ukraine could actually gain quite a lot."
He would not be drawn on whether that could mean Ukraine giving up territory, but said that "any negotiation is going to involve things that the other side don't like".
He added: "I think that the appeal to Ukraine would be part of that negotiation would be that Ukraine would become a full part of NATO. Now, Putin would hate that... but that would have to be part of the deal.
"If there were territorial concessions, that's all for the negotiations."
Pressed on if he thinks Ukraine should be open to territorial concessions, he said: "I'm not playing your silly game. I think there should be peace talks."

He added that while former prime minister Boris Johnson, a staunch backer of Ukraine, wants "the war to go on forever... all wars end either in negotiation, with concessions or annihilation".
Armed conflict in eastern Ukraine erupted in early 2014 following Russia's annexation of Crimea, and escalated in February 2022 when Vladimir Putin ordered a full-scale invasion.
Mr Farage previously drew criticism for his views on the conflict during the UK's general election campaign, when he said the West "provoked" Russia into the invasion with NATO's and the EU's expansion.
He ultimately won the seat for Clacton in Essex, but has since faced criticism for not spending enough time in his constituency.
Asked about this during his interview, Mr Farage said: "I've just exchanged contracts on the house that I'll be living there in, is that good enough?"
He also questioned how much time Prime Minister Sir Keir Starmer spends in his constituency, or Lib Dem leader Ed Davey, saying things were different for party leaders than backbench MPs.
"I am representing Clacton, yes, but I'm also leading a national political party which is rapidly rising in the polls, which we have to build from the ground up," he said.
"Today is Friday. Very often MPs are in constituencies on Friday. I'm in Wales, we're having an inaugural Reform UK conference here. We're looking to the Senedd elections.
"Tomorrow, I'll be in Exeter. If you're a national party leader, it's different."
