This is an article I've written for The Spectator magazine called 'What does David Cameron really think?'. It was also broadcast on Radio 4 on Saturday, 16 February. From Friday, 22 February it can also be downloaded as a Radio 4 podcast.
He is the longest serving of our major party leaders. He could be prime minister next year. He has had publicity that many a politician would kill for. Yet how many voters can answer a simple question 鈥 what does David Cameron really think?
That is what I have been trying to do for a documentary on 大象传媒 Radio 4. My producer Martin Rosenbaum and I have spoken to those who know Cameron best 鈥 his friends, his colleagues and a few of those who he鈥檚 crossed over the years.
Eighteen months ago we made a programme which asked the same question about the man who then looked set to be the next occupant of 10 Downing Street 鈥 Gordon Brown. Our aim then and now was to examine the values and the influences upon the man who would be Prime Minister rather than their policies. We鈥檝e been struck by how much harder our task has been this time around.
Brown had been at the top of government for 10 years. Cameron has never held office. Brown had just had a vast compendium of his speeches published and, as a young man, had written a book outlining his political philosophy.
Not so Cameron. The non political influences on Brown 鈥 in particular, his father鈥檚 religious teaching and the impact of almost losing his sight 鈥 were already well documented. In comparison, much less is known about how Cameron鈥檚 background shaped him.
The influences on the Tory leader are, for many, summed up by just two photographs. The first shows a young Cameron strutting in tailcoats alongside fellow Old Etonian, Boris Johnson, in a portrait of .
Both are now bidding to prove that association with the braying boys of the Bullingdon Club is not a bar to high office. The second finds Cameron lurking in the shadows on Black Wednesday watching his boss Norman Lamont announce that he was giving up the costly struggle to keep the pound in the ERM.
Some Labour politicians dream of deploying these two politically toxic images to portray Cameron as a privileged young Tory toff who bears some responsibility for the economic humiliation of the Major years. Others fear that this strategy will be no more likely to succeed than Tory attacks on Tony Blair for his membership of CND.
They recognise that, important though they are, those images tell only part of the Cameron story. They do not explain the long political journey he has taken. In 1996 young candidate Cameron rallied his party Conference with a call for a return to a tax-cutting agenda and to fight Labour鈥檚 plans to tame the 鈥淏ritish lion鈥 and turn her into a 鈥渇ederalist pussycat鈥. A decade later Cameron, now as leader, was telling his party to embrace gay marriage, social justice and social responsibility.
There are three other images from the album of influences on David Cameron which help explain that journey. The first is of his wife, Samantha; the second is his severely disabled son, Ivan; the third is the face of defeat. Each contributed to converting him - albeit much later than many of his friends - to the idea of 鈥渕odernising鈥 the Tory party.
Nicholas Boles, one of the earliest disciples of the need for the Tories to change radically, credits Samantha Cameron with 鈥渄ragging鈥 her husband 鈥渢o see the world as she saw it鈥. Boles says she forced the Tory leader to understand that Section 28 (the ban on the 鈥減romotion鈥 of homosexuality in schools) was 鈥渁n attempt to stigmatise a particular group鈥.
The Tory Party had treated Cameron so well, Boles argues, that it took Sam to make him understand other people鈥檚 hatred of it. A surprising role, perhaps, for the daughter of a baronet whose job is selling 拢950 handbags.
It was the birth of their severely disabled child, Ivan, which forced the Camerons to live their lives as many others live theirs - dependent on public services. Night after night spent sleeping on hospital floors changed the man who鈥檇 come from a 鈥渞arefied background鈥 says Ian Birrell who met Cameron as Deputy Editor of the Independent but befriended him as the fellow father of a very disabled child.
The experience did more than make Cameron a small c 鈥渃onservative鈥 when it comes to the funding of the NHS. It also filled him with frustration about its bureaucracy and fuelled his belief that the state needs to create the conditions in which voluntary organisations can thrive.
However, it took the Tory defeat of 2005 to finally turn Cameron from archetypal Tory boy to arch Tory moderniser. Danny Finklestein, the Times columnist, met Cameron when he was head of research at Conservative Central Office in Smith Square.
They were part of a group of Tory modernisers who used to talk politics over pizzas. He says that labelling the Cameroons 鈥渢he Notting Hill set鈥 misses the point. They are, he says, 鈥渢he Smith Square set鈥 whose shared experience of defeat forged their politics and distinguishes them from the Tories who came before.
Opponents would, no doubt, add a fourth image of Cameron - the PR man. All these images may help explain the political journey Cameron has undertaken but they cannot predict its eventual destination.
And that is where friends of Cameron become rather hazy. Faced by choices about governing rather than political positioning they cannot spell out what he would do.
Take just, one example, Europe. It鈥檚 one thing to instruct your party to stop 鈥渙bsessing鈥 about the issue. It鈥檚 quite another to decide whether to betray your activists who believe you are committed to renegotiating Britain鈥檚 relationship with the EU or to pick a long, lonely and, potentially, futile fight with the European leaders you鈥檝e fought so hard to join.
Put this or other choices on tax or climate change or social justice or social responsibility to a member of Team Cameron and they soon reply 鈥淎h but he is a pragmatist鈥. In this sense he is not a moderniser but a tradition-aliser harking back to the days not just before Thatcher but before Heath and 鈥淪elsdon Man鈥.
Douglas Hurd, Cameron's predecessor as MP for Witney, says, with some proprietorial pride, that he is a young man who is learning on the job. Rest assured that between now and the next election Gordon Brown will work hard to flush out the answers that I failed to get.
Whilst making this programme I鈥檝e had an uneasy feeling of d茅j脿 vu. Fourteen years ago I struggled to pin down what another young opposition leader really thought. People said he didn鈥檛 believe very much at all. Pinning down Tony Blair proved so tricky in 1994 that Panorama scrapped its planned profile. It鈥檚 a mistake I vowed not to repeat.
