Which jockey was imprisoned for tax irregularities in 1987?

Lester Piggott? Bet he didn't get a lot of chicks.

He failed to get away with tax fraud when he wrote the agreed settlement cheque front an undeclared bank account Duh!

what a shame that he couldn't be bothered to fill in his tax forms maybe he thought he'd get away with it? lost his knighthood because of it too.

one of the greatest riders but a tax cheat nonetheless.
