Why? If corporations are taxed to the point where there are negligible profits they will cease to do business in Britain. As corporations leave for other markets (or simply go out of business) so will the jobs. That's not to say corporations should not be taxed (although a coherent argument could be made for zero corporation tax), but certainly taxing corporations out of existence is a bad idea.
