Soon-to-be Captain Sir Tom Moore is to be knighted by the Queen at Windsor Castle on Friday.
The 100-year-old war veteran raised over £32m for NHS charities having initially set out a target of £1,000 for walking laps of his garden in Marston Moretaine, Bedfordshire.
Prime Minister Boris Johnson made a special nomination for Capt Moore to be knighted in May.
Royal investitures were put on hold during the pandemic lockdown. Ceremonies scheduled to take place in June and July at Buckingham Palace and the Palace of Holyroodhouse were delayed.
People have been asked not to go to Windsor and there will be no viewpoint.
The Queen will carry out the engagement in person after staying in Windsor during lockdown.
Capt Moore was given the honorary title of colonel on his 100th birthday. He will travel to the royal residence with members of his family.
The monarch will knight the former British Army officer with the sword that belonged to her father, George VI. He will also receive the insignia of Knight Bachelor.
Following the announcement, Capt Sir Tom said “I hope she’s not very heavy-handed with the sword as by then I might be rather a poor old weak soul”.
