Russia gloats

Needless to say, Moscow isn't sorry to see BoJo go. Maria Zakharova, spokeswoman for the Russian ministry of Foreign Affairs, didn't hold back in comments on her Telegram platform account. Recent actions of the British government, she said, were "the habits of savages. Those who call themselves the "civilized world", advanced countries, developed democracies, have become not just a universal laughing stock. It’s worse than that. They evoke a sense of disgust in those who they themselves are accustomed to baselessly disdain."

She added that ‘the ruling Conservative Party of Britain has created largely insurmountable economic difficulties for ordinary and industrious Britons. The problem is not ours. It is a British problem. But London is actively trying to solve its internal issues at the expense of external factors: participation in anti-Russian activities, provocations in Ukraine, global economic destabilization and financial piracy."

Zakharova was in fact echoing criticism that Johnson faced at home by those accusing him of diverting his own political problems at home by taking an aggressive stance on foreign policy.

Kyiv grateful but wary

Johnson remained remarkably popular in Ukraine, notwithstanding his implosion back at home, recently tallying 90% approval by Ukrainians in a Lord Ashcroft Polls survey.

The British leader even had a Ukrainian city street and a bakery's croissant named after him. Last week, Johnson was made an honorary citizen of Odessa, with Mayor Gennadiy Trukhanov, declaring Johnson the ‘main ally and friend’ of Ukraine.

But Kyiv is focused on winning a war, and will waste no time looking back. Zelensky will be focused on maintaining maximum British support from whoever replaces Johnson as Conservative party chief, while keeping an eye on the Labour opposition.

The succession question

Johnson's replacement, whoever that may be, must face the difficult task of rebuilding a parliament in disarray as well as play a major role in stabilizing the geopolitical unrest triggered by the invasion of Ukraine.

In his resignation speech Thursday, Johnson declared: "We in the UK will continue to back your fight for freedom for as long as it takes."

However, it is far more likely that active British support for Ukraine will dwindle in the coming weeks and months as UK parliamentary and media attention focuses on the internal brawls and corruption that have become commonplace in British politics, while the economic impact of the war continues to accumulate.

Truss, who has been compared to Margaret Thatcher, may take an even harder line.

Whoever emerges as the next British Prime Minister is unlikely to arrive in office with a stance ostensibly much different than Johnson's, and at least one leading candidate, Foreign Secretary Liz Truss, who has been compared to Margaret Thatcher, may take an even harder line.

In an interview last month with the BBC, Truss' Russian counterpart, Sergey Lavrov, made it clear that the Kremlin was skeptical of the various members of the Tory cabinet. Still, by October, when a replacement is expected, we will likely be in a very different phase of the conflict. Whoever is to replace Johnson will need to trade in the bluster and rhetoric for pure skills in negotiation — with Western allies, regional players, Ukraine — and even Russia itself.
