My main commitment is to Caudwell Children. I put more than £1m a year into the charity, besides a lot of time and effort.

I'd much rather leave £2bn to charity, or £3bn or £4bn, than £1bn. That is my motivation to carry on working as hard as I do.

I believe in workers' rights when people are doing a good job.

I believe in workers rights when people are doing a good job.

Sometimes your worst competitors are the ones which are dying because they do stupid things.
