The Guardian’s central and eastern Europe correspondent, Shaun Walker, talks through a seismic week, as the president sidelined Kyiv and other European capitals from negotiations on the ending the war and then called into question the future of US support for Europe’s security altogether

Last Monday, the Guardian’s central and eastern European correspondent, Shaun Walker , sat down in Kyiv to interview the Ukrainian president, Volodymyr Zelenskyy.

The conversation, Walker explains, was dominated by what Zelenskyy hoped to achieve in any upcoming talks on a ceasefire deal in Ukraine. The president outlined his red lines, too: that the US would have to be involved in some way in securing Ukrainian security once the fighting stopped; and that any negotiations over its future would have to involve Ukraine itself.
