Joe Biden has called off a four-day trip to Germany this week that had been intended to culminate in a summit to discuss Volodymyr Zelenskyy’s “victory plan” for Ukraine.

The White House said on Tuesday evening that the president would stay at home “to oversee preparations for and the response” to Hurricane Milton, which is expected to make landfall in Florida on Wednesday.

It was not clear how Biden’s absence would affect the planned summit, the first time world leaders were due to gather at the Ramstein US airbase, normally the location of a regular meeting of defence ministers to discuss military aid for Kyiv.
