SIR Tory leader David Cameron, right, often cycles to work but he is always followed by a car carrying his personal belongings, while Tony Blair and Sir Menzies Campbell religiously travel in chauffeur-driven limos.

According to recent party political broadcasts all three leaders profess to have gone green, but I fear it's only a ploy for political gain.

In the mid-1920s there were an estimated 66,000 cars on Britain's roads but now there are more than 25million, so goodness knows what the total will be in the next few decades.

Experts continually warn us about global warming yet more and more cars are being manufactured to further pollute the atmosphere and I'll wager that most environmentalists possess one too.

Of course, it's now a worldwide concern so it is imperative that nations work together to find a solution before it's too late.
