The market is a brilliant system for the exchange of goods and services, but it doesn't protect the environment unless it's regulated, it doesn't train your workforce unless it's regulated, and it doesn't give you the long-term investment you want.

I don't work hard enough. If I had worked harder I might have been prime minister.

When I was leader of the GLC, by the time I had been in control for three years, the difference in pay between the cleaner and the director general was a four-to-one ratio. I find that attractive.

The people I really most admire are Robert Kennedy and Franklin Roosevelt. If you know someone, it is very hard to revere them.

I don't just denounce suicide bombers. I denounce those governments which use indiscriminate slaughter to advance their foreign policy.

Everyone changes all the time.

I've always been a workaholic. I reckon, on average, I've had less than one day a year off in my working career.
