Health Secretary Steve Barclay has been confronted about scandalous ambulance waiting times during an interview by an angry voter who told him: "You've done b****r all about it."
Mr Barclay, who was appointed by Boris Johnson last month, looked uncomfortable as the woman heckled him over the healthcare crisis.
She voiced her fury about lives lost as people endure long delays for paramedics in emergencies - with elderly patients facing 14 hour waits in parts of the UK.
The cabinet member, who has backed Rishi Sunak in the Tory leadership race, was mid-sentence when the woman was heard shouting out: "Are you going to do anything about the ambulances waiting and the people dying out?"
Despite his initial efforts to ignore her, the woman continued to confront him over the Tories' appalling record in government.
She said: "Don't you think 12 years is long enough... You've done b****r all about it, people have died and all you've done is nothing."
Mr Barclay was filmed squirming as the woman made her point clear before walking away, leaving him looking stunned.

The confrontation happened outside Moorfields Eye Hospital in Old Street, central London.
Health service chiefs have become increasingly alarmed at the amount of time it takes to respond to emergency calls in some parts of the country.
Today the Mirror reported that elderly patients face 14-hour ambulance waits for falls, with one dying after getting trapped under a bed, a regulator warned.
The delays have led the Care Quality Commission to rate South Central Ambulance Service (SCAS) NHS Foundation Trust as inadequate.
Its damning report said one patient waited 14 hours for help from the service, which serves seven million people in Hampshire, Buckinghamshire, Berkshire and Oxfordshire.
The CQC said delays also contributed to the death of an elderly patient who had fallen and got trapped under their bed.
Deanna Westwood, CQC director for the south, said: “Staff told us about the day before our inspection when a patient had been on the floor for up to 14 hours, following a fall, before the crew arrived."
Following the heated interaction, Mr Barclay said that reducing ambulance waiting times is an "absolute priority" for the Government.
He told the PA news agency: "There's a range of measures that we're taking.
"We're looking at conveyance rates in ambulances, we're looking at how we address variation in performance, we're looking at funding - an extra £150 million to the ambulance service, a further £50 million into call centres, for 111 and 999, in terms of call handling, a further £30 million into St John Ambulance around the auxiliary ambulance performance.
"We're also then looking at what happens with the ambulance handovers, so emergency departments, how we triage those, how we look at the allocation of this within the system.
"Of course, that is all connected to delayed discharge and people being ready to leave hospital who are not doing so, and that's about the integration of care between social care and hospitals.
"So there's a range of issues within how we deliver on ambulances, but it's an absolute priority both for the Government and for NHS England."
And last week we reported how an 87-year-old man was left shivering in a makeshift tent on a concrete floor during an agonising 15-hour wait for an ambulance in Cornwall.
Retired welder David Wakeley, 87, who suffers from prostate cancer, endured the horrifying wait after falling at his home in Cornwall on Monday night.
Son-in-law Trevor Crane, 64, told The Mirror: “The system is just broken.
“As a family we know the NHS staff are great and trying their best but you have to ask how things like this keep happening?
“It just seems like no one cares and no one is willing to fix it.”
