Jean-Claude Juncker has attacked Ursula von der Leyen, his successor as European Commission president, for starting a “stupid vaccine war” with Britain. Mr Juncker said he was “not a fan” of Mrs von der Leyen’s threat of imposing an export ban on EU manufactured jabs to the UK and warned it would “create major reputational damage” for the bloc. “We used to be the world’s free trade champion,” he said as EU leaders meet for a summit to discuss the potential ban, “We have to pull back from a vaccine war.” Mr Juncker also criticised the EU for being too slow in approving and buying vaccines, branding the bloc as “too cautious” and “budget conscious” in an interview with BBC’s HardTalk. The veteran politician led the commission from 2014 to 2019, which included the period after the Brexit referendum. “We have special relations with Britain, there’s room for dialogue […] nobody in Britain, nobody in Europe understands why we are witnessing such a stupid vaccine war,” Mr Juncker said.
