Quote from denner:
I read about this issue a few years ago when several other prominent sports figures were involved as well. If I remember correctly, at the time, they may have granted special exemptions once they realized the major impact it would have on marquee events such as Wimbledon and The British Open.
On the other hand, I seem to remember that alot of prominent musicians got caught in the crosshairs of the "taxman" back in the 60's/70's. Led Zeppelin, Pink Floyd, etc, etc...were figuring out ways to get out of the UK as much as possible to avoid the 90+% tax "rape".
