Zelenskyy hopes for "constructive" talks with US envoy after Trump's "dictator" remark

Volodymyr Zelenskyy is hoping for constructive talks with US special envoy Keith Kellogg, a day after trading barbs with US President Donald Trump, who called the Ukrainian leader a "dictator". Mr Zelenskyy proceeded to accuse Mr Trump of succumbing to what he calls "Russian disinformation". Tensions have run high between the two leaders following high-level talks between top US and Russian officials that did not include either Ukraine or Europe. Stuart Smith and Nick Harper report.
