I think you're being a bit hard on Tony, Lutonian.
He has overseen a robust economy, introduced the Minimum Wage (when the Tories claimed it would cost 3 million jobs), tried to devolve some power to the regions, been active in the Middle East peace process, has raised the profile of country around the globe, etc.
I think you could hardly call him a "liberal". Quite frankly he's more conservative on many moral issues than almost all of the Tory party. He behaves as a good family man should as well (which makes a change from the past few governments).
And any man who puts world freedom ahead of his own party's bitter little prejudices is alright by me.
How does he "weaken" the family?
