BERLIN: Ukrainian President Volodymyr Zelenskyy will visit Berlin on Wednesday to join German Chancellor Friedrich Merz for talks with European and U.S. leaders ahead of the Trump-Putin summit later this week, the German government said. Merz has convened a series of virtual meetings on Wednesday in an attempt to have the voice of European and Ukraine’s leaders heard ahead of a summit that they have been sidelined from. Zelenskyy is due to meet with European leaders first, to prepare for a virtual call with U.S. President Donald Trump and Vice President JD Vance about an hour later.
