LONDON: Britain does not need a vacuum at the heart of government right now due to the gravity of the Ukraine crisis, a junior foreign minister said on Sunday when asked if Prime Minister Boris Johnson should resign over lockdown parties.

Johnson has received a police questionnaire as part of an investigation into parties at Downing Street during COVID lockdowns. He has repeatedly been asked if he would resign.
