Keir Starmer should show leadership over the Ukraine war by pushing for $300bn (£243bn) of frozen Russian assets to be used to fund Kyiv’s military, the financier turned activist Bill Browder has said.

Speaking on the sidelines of the World Economic Forum in Davos, Browder warned that if US military support for Ukraine dried up, Russia would make territorial gains in the near-three-year long conflict, forcing millions of Ukrainians to flee the country.
