WW2 veteran Captain Tom Moore has now raised more than £14million for the NHS.
The 99-year-old has inspired the donation of the eye-watering sum by walking along his garden in Bedfordshire 100 times.
At the point that he completed the walk, Captain Moore this morning had raised £12.2million.
Just a few short hours later that figure had been increased to £14.4million.
Chancellor Rishi Sunak congratulated the Captain on his endeavours.

"A massive congratulations to you on your hundredth lap," Mr Sunak said.
"What you've done is extraordinary, and the millions of pounds you've raised for the NHS will be put to good use as we continue to tackle this virus together.
"As an adopted Yorkshireman I've come to recognise true Yorkshire grit, and your story is an inspiration to us all. It just goes to show that British spirit is as strong as it's ever been."
Captain Moore took the time to offer a few choice words of hope after completing his challenge.
Speaking at the finish line, he said he felt "fine" and that he was "surrounded by the right sort of people".
Of the coronavirus pandemic, he told BBC Breakfast: "We will get through it in the end but it might take time, but at the end of the day we shall all be okay again... the sun will shine on you again and the clouds will go away."
Originally from Keighley in West Yorkshire, Mr Moore trained as a civil engineer before enlisting in the Army for the Second World War, rising to captain and serving in India and Burma.
When he was posted to serve in India in October 1941, it took his Battalion six weeks by sea to arrive there.
During his time in south Asia Captain Moore was instructed to start a motorcycling course before the Battalion was moved on to Calcutta - a road journey which took three weeks in Monsoon season.
Back in the UK Captain Moore was sent on a course at The Armoured Fighting Vehicle School in Bovington.
He was kept there as an instructor until they were demobilised.
Mr Moore began raising funds to thank NHS staff who treated him for a broken hip.
