Labour MPs deride David Cameron's rooftop wind turbine as petty tokenism, but what of their own leader's attempts to curry favour with the green lobby? In an interview with The Times last week, Gordon Brown began flashing his environmental credentials by bragging about the solar panels at his home in Fife.
"Very quietly, we put solar panels on our home in Scotland quite some time ago," he said. "We have been operating with solar power for some time."
Not quite true, says the London-based renewable energy supplier Solar Century. The Browns' home is apparently fitted with solar thermal hot water collectors, which provide hot baths but no electricity. Says a spokesman: "So much for trying to score cheap points!"
