binners - nothing we can do about corporation tax, if we have different rules then they'll just not bother trading with the UK or our prices will rise. As we're not self sufficient we'd be cutting our nose off to spite our face.
In general the public could ensure they buy British from British companies, this would help the matter but we're talking years for it to have any impact. But there's nothing to stop you or I making that change right now.
We'd be better off closing the loopholes that many companies that are registered in the UK use to avoid paying tax while staying within the letter of the law.
