British Prime Minister Boris Johnson believes that the next few months will be difficult for Britain due to Russian aggression. He is also convinced of the victory of the Ukrainian people and the restoration of Great Britain.

"We must not give in to Putin's aggression. The next few months will be tough but I am convinced Britain's bounceback will be golden," he said on Twitter on Sunday night.

He also expressed confidence in the victory of the Ukrainian people.

"In this brutal arm wrestle, the Ukrainian people can and will win. And so will Britain," Johnson said.
