Politico writes about it.

The article says that the news of the politician's resignation discouraged his allies in Kyiv.

It is noted that in this regard, the Ukrainian authorities fear that London will no longer adhere to the policy of "close ties of friendship with Ukraine."

In particular, Ukrainian Foreign Minister Dmitry Kuleba expressed confidence that no one can replace Johnson.

He drew attention to the "chemistry" between Ukrainian President Volodymyr Zelensky and Johnson.

In addition, one of Johnson's longtime political allies told the newspaper that the prime minister's departure posed "real risks" for Ukraine. 

Earlier, a petition appeared on the website of Ukrainian President Volodymyr Zelensky to grant Ukrainian citizenship to Boris Johnson and nominate him as a candidate for the post of Prime Minister of Ukraine.

On July 7, Johnson announced his decision to step down as Prime Minister of Great Britain and leader of the country's Conservative Party.
