If you know your life chances are greatly reduced, should you be in a position to take out life insurance if that knowledge is not available to the insurers?

Scientists should not do animal testing if there is any alternative, but subject to that, I would support it on grounds of the medical benefits.

I am proud of the fact that the U.K. is an open trading country. I welcome inward investment such as that of Nissan, and the takeover of struggling British companies by foreign companies who turn them around, as in the case of Jaguar Land Rover.
