Nile Gardiner, a former adviser to Margaret Thatcher, told Express.co.uk that the UK is “by far the leading power in Europe” when it comes to “responding to Russian aggression”. This, he said, is the result of Brexit, which he described as a “game changer” for Britain in terms of “leadership on the world stage”. Mr Gardiner said the country is “much more confident, assertive and willing to project power” now that it has left the EU.
It comes as the UK has been widely praised for its response to Ukraine.
Ukrainian President Volodymyr Zelensky described Mr Johnson as “an example”, suggesting other countries were “carrying out a balancing act” when it comes to the war between Russia and Ukraine.
He said: “Britain is definitely on our side.
“This is not a balancing act.
“Britain sees no alternative way out of this situation. Britain wants Ukraine to win and Russia to lose.”
Speaking to The Economist, he added: “Johnson is a leader who helps more.
“Leaders of countries react based on how their constituents act.
“In this case, Johnson is an example.”
“The UK is now much more confident, assertive and willing to project power than it was in the EU.
“I think Brexit was a release for Britain in terms of leadership on the world stage.
“It was a game-changer.”
The UK, alongside its NATO allies, imposed a broad set of sanctions on Russia, began phasing out Russian energy and supplied arms to Ukraine.
Some EU countries, such as France and Germany, have been criticized for their response to the crisis.
Mr Zelensky accused German Chancellor Olaf Scholz of contributing to a new “Berlin Wall” in Europe, citing their initial failure to stop the controversial Nord Stream 2 pipeline as an example.
Meanwhile, Polish Prime Minister Mateusz Morawiecki criticized French President Emmanuel Macron for continuing to meet Vladimir Putin.
