The 100-year-old, who raised almost £33m for NHS charities by walking laps of his garden, was admitted to Bedford Hospital on Sunday.
Liz Lees MBE, Chief Nurse, Bedfordshire Hospitals NHS Foundation Trust said: “It has been our immense privilege to care for Captain Sir Tom Moore.
“We share our deepest condolences and sympathies with his family and loved ones at this incredibly sad time. We’d also like to say thank you, and pay tribute to Captain Sir Tom Moore for the remarkable contribution he has made to the NHS.”
We will not be providing any further comment and ask members of the public and media to respect the privacy of Captain Sir Tom’s family at this difficult time.
The Army veteran won the nation’s hearts by walking 100 laps of his garden in Marston Moretaine in Bedfordshire last year during the first lockdown, raising money for NHS Charities Together.
He was credited with lifting the nations’s spirits and his saying “tomorrow will be a good day” trended on social media.
He was knighted by the Queen in July in a special ceremony at Windsor Castle.
