text: Right now, you may feel that you know the inside of David Cameron’s kitchens – yes, both of them – better than your own. Two weeks ago the Prime Minister let the BBC film him preparing lunch at his home in his Oxfordshire constituency. Then this weekend it was the No 10 kitchen that was the focus of attention as he made a pitch for the family vote by being pictured at breakfast with wife Samantha and their three children.

Making a point: Mr Cameron chats with his children over the No 10 breakfast table during the ITV show . And tonight you can see the Downing Street kitchen all over again as they once more gather round the breakfast table (white marble and costing £750), this time for the cameras of ITV News. When he invited the BBC film crew into his constituency kitchen, Mr Cameron blundered into a row after admitting he did not want a third term as Prime Minister. This time round, he may have thought he was on safer ground being questioned by his own family over the No 10 breakfast table. But the chat showed them teasing the Prime Minister after he appeared to confuse the Disney film Frozen for a book. He asked his four-year-old daughter Florence about her fairy costume for World Book Day, adding: ‘Why are you not going as Elsa [from Frozen]? That’s what I want to know.’ His wife Samantha answered, saying: ‘Because it’s not a book.’ The PM laughed awkwardly before attempting to change the subject, asking: ‘Anyway, have you got some interesting views on school food?’ One of his older children replied bluntly: ‘It’s absolutely disgusting. I brought in a chip that was half green.’ Mr Cameron has previously said he shares the irritation of many parents at hearing the song Let It Go from Frozen sung too many times.

Phenomenon: During the show, Mr Cameron is teased for appearing to confuse Disney film Frozen for a book . Earlier this year he said Florence regularly ‘launches into song’ in front of his security guards. He said: ‘I don’t know all the words but I have listened to it being sung more times than I care to remember.’ Mr Cameron was filmed at home with his family for an ITV profile due to be aired tonight, although his children’s faces were not shown on camera. His wife said the breakfast-time teasing was typical of the way the Prime Minister’s family keep him ‘grounded’, saying: ‘They take the mick all day long.’ She said oldest daughter Nancy, 11, and son Elwen, nine, had also teased their sister as ‘really uncool’ after she came home from school saying: ‘My daddy is the Prime Minister.’ Mrs Cameron said Florence later told her grandmother: ‘Don’t tell anyone but my daddy’s the Prime Minister.’ In the interview with ITV News political editor Tom Bradby, Mr Cameron also spoke frankly about the death of the couple’s disabled son Ivan. Humble: Samantha Cameron told the ITV show that the family often teased the Prime Minister over breakfast as a way of keeping him ‘grounded’. She said: ‘They take the mick all day long' Caring: David Cameron took a break from the campaign trail on Saturday to feed a newborn lamb in Witney . He said: ‘It’s everyone’s dread to lose a child. You lose someone you love so much, so young. It does hit you like nothing else and there is a bit of you that thinks, well if you can face that sort of challenge in your life, then it puts everything else into perspective.’ Mr Cameron was also asked about his background. He said: ‘I went to a very posh school, I had a very privileged upbringing with parents who were incredibly loving and brilliant. I’ve never tried to hide that, I’m not going to change my accent or talk in a different way.’ Spotlight – David Cameron: Tonight will be broadcast on ITV at 7.30pm.
