“The clown is going,” said Vyacheslav Volodin, the speaker of Russia’s parliament after the fall of Boris Johnson. “He is one of the main ideologues of the war against Russia until the last Ukrainian. European leaders should think about where such a policy leads.”Maria Zakharova, spokesperson of the Foreign Ministry in the Kremlin, declared: “The moral of the story is: do not seek to destroy Russia: it cannot be destroyed. You can break your teeth on it – and then choke on them.”Mr Johnson may regard these insults as badges of honour. He certainly will not object to being called the leader in the support of Ukraine against Russian aggression: although the volume of America’s military and financial support to Kyiv outweighs those from other Western states.But the UK is now leaderless, without a prime minister who wields any authority. To continue with the Russian theme, Boris Johnson is now the head of a Potemkin government – a false and hollow structure. This could continue for months, and it is a vulnerable place for the country to be in these uncertain times.Recommended More
