The nation mourned with the Queen this year as she said a final, dignified farewell to her husband of more than 70 years.

Sir Tom’s fundraising efforts raised more than £32 million for the NHS when he walked 100 laps of his garden before his 100th birthday in April 2020, and he remained an inspiration in the months which followed.
The charity work and public service of Sir David Amess was also remembered in tributes to the Southend West MP after he was fatally stabbed during a constituency surgery in October.
Sir David, 69, who was described by Prime Minister Boris Johnson as “one of the kindest, nicest, most gentle people in politics”, had been an MP since 1983 and Southend was granted city status in his memory.
