Ukraine's first lady Olena Zelenska has met the Princess of Wales ahead of the funeral of Queen Elizabeth II, APA reports citing BBC.
Sunday's audience at Buckingham Palace took place shortly after Ms Zelenska visited Westminster Hall to see the Queen lying in state.
World leaders and dignitaries have been been arriving into London ahead of the funeral of the late monarch on Monday.
US President Joe Biden also saw the lying in state and said the "world is better" because of Queen Elizabeth.
The Queen is lying-in-state until Monday morning, and people have been queuing for hours to see the coffin.
Ms Zelenska's visit to the UK comes after her husband, President Volodymyr Zelensky, signed a book of condolence for the Queen at the British embassy in Kyiv.
The UK's ambassador in Kyiv, Melinda Simmons, said she was "deeply honoured" by the president's gesture "given all else that is happening in [Ukraine] at this time".
