Something very worrying has been going on at Scotland Yard. We now know that in dealing with the phone-hacking affair at the 'News of the World,' they cut short their original inquiry; suppressed evidence; misled the public and the press; concealed information and broke the law. Why?

The friends of tabloid newspapers often point out that their journalism exists only because millions of people pay money to read it.

The Murdoch-owned 'Sunday Times' has an appalling history of involvement in illegal activity. And it's because they're Sunday papers; they're trying to get scoops that the dailies haven't got.

It's the tabloids, with their intense commercial need to get scoops to bring in readers, that run a regime of fear, where reporters are bullied, shouted at. That's where things go wrong.

Notoriously, in 1975, Murdoch abused his position as a newspaper owner to support a plot that ousted the democratically elected prime minister of Australia, Gough Whitlam, who had dared to wander away from the mogul's path.

I spent two years working on building sites, working on the railways as a guard and in a racing stable, exercising racehorses. I learnt to build relationships. The experience of not being stuck in some middle-class bubble taught me things that being at university hadn't.

You don't get shouted at at the 'Guardian.' Nobody bullies you at the paper; nobody tells you what to write. Now, I love working in that atmosphere; I am free to research and write what I want.

It is an odd thing about newspapers that they live by exposure, yet they keep their own worlds concealed.

I've learnt that your life is more interesting and fulfilling when you don't lead it in a straight line and you go off on zigzags. I've made it a rule that if life becomes too comfortable and easy, I'll disrupt it.

Once, the world was full of mysteries, some of them frightening, some of them wonderful, some of them merely fascinating. Now, it can be a banal and predictable place, the tracks of daily life so well-beaten and defined, our culture awash with the imbecile obvious, our existence suffocating in safety. But mysteries remain.

Back in the 1980s, the 'News of the World' had specialised in digging into the privacy of criminals. In the 1990s, enriched by the excavation of Princess Diana's volatile life, they had widened their work to mine the activities of any celebrity, any public figure.

The effect of climate change is not simply to reduce rain during the summer months, but also to increase the number of torrential storms. When the rain falls that hard and fast, it cannot sink into the ground and go down to the aquifers.
