David Cameron was repeatedly heckled by pensioners on Tuesday afternoon, as he spoke at an event hosted by the Age UK charity.
As the video above shows, the prime minister had trouble defending the coalition's record on the NHS during a question and answer session in the face of the less than impressed audience.
Cameron was speaking in central-London a day after he surprised Westminster by announcing he intended to retire as prime minister at the end of his second term - assuming he is given one by voters.
He defended his pledge today, after Labour accused him of arrogance given he has not even been elected to a second term yet. The prime minister said he was "taking absolutely nothing for granted" and that he thought voters would see his comment about his future as "a very reasonable, sensible thing to say".
"My entire focus is on the next 44 days and the general election, which will decide which team runs this country for the next five years," he said. "What I did in my kitchen is I gave a very straight answer to a very straight question and I think that people will understand that - that saying you want to serve a full second term for a full five years is a very reasonable, sensible thing to say."
After being heckled throughout his appearance, the prime minister told the audience: "Thank you for your lively interactions."
Cameron's decision to rule out a third term has effectively fire the starting gun on the next Conservative leadership election. In the BBC interview the prime minister named Theresa May, George Osborne and Boris Johnson as three possible successors. Ministers avoided shouted questions about the leadership as they attended this morning's cabinet meeting in Downing Street.
Johnson, who is seeking to return to the Commons as an MP in May, is widely assumed to have his eyes on the Tory leadership. He told LBC this morning there were "many candidates" for the job and played down the significance of Cameron's statement.
Tory Leadership Race
Boris Johnson(01 of07)
Open Image ModalTheresa May(02 of07)
Open Image ModalCurrent position: Home SecretaryRides: "Beyond The Borders"Odds to win: 4/1For: Politically, May is a shrewd and successful operator who has done a credible job as home secretary, a role that has tripped up many previous politicians. The first female chair of the Conservative Party. Also part of the trio named by Cameron as his possible successors.Against: A Tory minister recently described May as "100% charmless" and the only benefit that her appointment as leader would bring would be "net migration". She would be 63 by the time of the 2020 general election - the only woman, but also the oldest of the three frontrunners. (credit:PA/Composite)
George Osborne(03 of07)
Open Image ModalCurrent position: Chancellor Rides: "Red Box Makeover"Odds to win: 7/1For: Osborne has seen a turnaround in fortunes after stumbling at a few early budget hurdles. Last budget generally seen as a resounding success and management of the economy has arguably put Britain ahead of Europe in the recovery. Has had a personal makeover including his new close-cropped haircut dubbed 'The Osborne'. Also part of the trio named by Cameron as his possible successors.Against: His privileged background is well-known, and his membership of the Bullingdon Club - an Oxford dining society for the very rich, of which Cameron was also a member - particularly riles those who believe he does not have the common touch. He is considered a political heavyweight, but being a good chancellor does not necessarily translate to being a good party leader and prime minister, as recent history has shown
Sajid Javid(04 of07)
Open Image ModalCurrent position: Culture SecretaryRides: "Rising Star"Odds to win: 10/1For: Javid, the son of Pakistani immigrants, is the first of the Tory MPs elected in 2010 to become a cabinet minister.Against: Close to George Osborne, he may choose to give the Chancellor a clear path at the leadership.
Philip Hammond(05 of07)
Open Image ModalCurrent position: Defence SecretaryRides: "Stripped Down Defender"Odds to win: 10/1For: Erm...Against: Recently received a "slapping down" from Danny Alexander for publicly complaining about defence cuts.Also, he's possibly the most "beige" of all the prospective candidates.

Open Image ModalCurrent position: Tory Chief WhipRides: "Baccalaureate Backtrack" Odds to win: 100/1For: Gove is highly regarded within the Tory party as charming, polite and capable.Against: He has taken a bruising both from the public and other Tories for some of his proposals in his former job as Secretary of State for Education.
