The Queen has held her first in-person engagement since catching COVID, meeting Canadian prime minister Justin Trudeau.
The monarch held an audience with Mr Trudeau on Monday at Windsor Castle.
Mr Trudeau is in the UK for talks on the war in Ukraine with Prime Minister Boris Johnson and Dutch prime minister Mark Rutte.
The Queen, 95, tested positive for coronavirus on 20 February, just days after Prince Charles and the Duchess of Cornwall both contracted the virus.
Understood to be triple vaccinated, she is thought to have experienced mild cold-like symptoms.
