Diplomats from the UK, France, Germany, Ukraine and the US will hold fresh talks in London on Wednesday aimed at securing a ceasefire in the three-year war between Ukraine and Russia. The talks come amid growing speculation that Russia might be willing to halt its invasion along current front lines in return for significant concessions.

President Volodymyr Zelenskiy said on Tuesday Ukraine was ready for talks with Russia "in any format" once a ceasefire is set, while the Financial Times reported President Vladimir Putin had offered to halt Russia's invasion at the current front lines.

Russia and Ukraine blamed each other for breaking an Easter ceasefire announced by Vladimir Putin, with both sides accusing the other of carrying out attacks.
