KEITH NEWBERY Was it naivety or arrogance that did for Liam Fox?

Liam Fox did not deserve to hold down one of the great offices of state – and David Cameron should have ditched him at the first available opportunity.

This opinion is not based on what may or may not have happened during the defence secretary’s odd working relationship with his friend, Adam Werritty.

We have still not heard the half of it, and more damning facts will be drip-fed to the media in the days ahead despite his belated decision to resign.

No, Fox deserved to go because he had proved himself either far too stupid, arrogant or naive (I’m not sure which) to remain on the government front bench.

MPs in general – and ministers in particular – have never been under more intense scrutiny.

The expenses scandal merely confirmed what most voters had long suspected: that Westminster is not exactly crammed with the selfless and the altruistic.

It has more than its fair share of spivs and chancers, and as a result of heightened public suspicion, the media are ready to pounce on any hint of scandal. The need for openness and propriety in all things has never been more important.

Yet in this highly-charged atmosphere, Liam Fox thought he could get away with including his unauthorised, unaccredited ‘best man’ in sensitive discussions with everyone from a top American general to a British ambassador.

That is why he stands accused of being either stupid, arrogant or naive... you decide.

One must also query Werritty’s credentials as a ‘friend’, a relationship he clearly chose to exploit. As a self-styled ‘business consultant’ he may not have received any obvious financial benefit from his participation at these meetings, but they will not have done his future prospects any harm.

He was there for a purpose – and that was not to hold his old chum’s hand or provide any kind of moral support.

The only person to emerge from this peculiar and slightly tacky affair with any credit has been shadow defence secretary, Jim Murphy. He did not go snarling, Balls-like, on to the offensive at the first opportunity, choosing instead to adopt a more measured tone.

He has since been a dangerous combination of the forensic and the disdainful. He’s certainly one to watch for the future.

* Expect winter to be, err, a tad cold...

No sooner has the late heatwave become a fond memory, than the forecasters are busy promising us the sort of winter in which entire communities will disappear beneath snow-drifts and television crews.

Professionals are expected to respond accordingly, so councils have supplemented their stocks of grit and newspaper sub-editors have dusted off their wintry puns.

But it’s the so-called experts who continue to steal the show.

Take forecaster James Madden, from Exacta Weather, for example.

He said: “I expect the most frequent and heavy snowfalls to occur across many parts of the UK during November, December and January.”

I wonder how much he gets paid for providing the sort of ‘expertise’ which could be obtained from any moderately intelligent ten-year-old?
