New Prime Minister Liz Truss said she was “hugely honoured” to be the last premier to be appointed by the Queen.
Ms Truss went to Balmoral Castle on September 6 where the monarch asked her to form a government and become her 15th PM.
Two days later the Queen died, plunging the UK into 11 days of mourning, which climaxed on Monday with Her Late Majesty’s funeral.
