Boris Johnson has shared his "admiration and gratitude" for Captain Tom Moore on the war veteran's 100th birthday.
The former tank commander has raised more than £30million for the NHS Charities Together, after initially setting a target of £1,000.
Mr Moore aimed to complete 100 laps of his garden before his centennial birthday and managed to obtain the support of the entire nation.
The Prime Minister took to social media to share his praise of Captain Tom.
Mr Johnson said: "Captain Tom - today, on your 100th birthday, allow me to express the admiration and gratitude of a whole nation for your heroic fundraising mission."
He then shared a photo of the letter being sent out to the fundraising hero.
The Prime Minister's letter reads: "Every day I write to someone in our country to thank them for their service to others and to recognise them as a Point of Light in our lives.
"No-one epitomises a Point of Light more than you.
"So today, on your 100th birthday, allow me to express the admiration and gratitude of a whole nation for your heroic fundraising mission.
"You have touched our hearts, lifted our spirits and enabled millions to show their support for the wonderful men and women of our unique NHS. Because of their extraordinary courage and dedication our country will get through this difficult time and, in doing so, fulfil your optimism that tomorrow will indeed be a better day.
"So, congratulation on becoming the UK's 1362nd Point of Light, thank you for everything you have done and I wish you a very Happy Birthday!"
The Prime Minister signed the letter, "with all best wishes, yours sincerely, Boris Johnson".
The war veteran has been showered with praise and gifts for his 100th birthday, with many in awe of his staggering achievement for the NHS.
Captain Tom has been given a bespoke regimental blazer from his local tailors, the McLaren Formula 1 Team presented him with his own helmet to show their appreciation and a birthday card from the Queen.
