Ashcroft's guilty secrets

It would be interesting to know how much tax Ashcroft has paid in the UK (both income tax and corporation tax on his UK companies).
After all if Ashcroft had donated millions to the Tories over the past 10 years, he should have made a healthy profit on his UK trading activities and thus paid a bucketload of corporation tax? NOT.

I also wonder exaxctly how much income tax he has actually paid in the UK? I expect it to be close to zero; the Belizian shyster.
