Who? Christopher Stewart-Moore, 54-year-old sports law partner at Ralph Davis in London.

Why is he in the news? Represents Kieren Fallon, the jockey at the centre of a media storm after letting slip a big lead at Lingfield.

Undercover News of the World journalists - including Mazher Mahmood, the 'fake sheik' who once caught out the Countess of Wessex - claim that Mr Fallon tipped the winning horse Rye Thunder to them three hours before the race.

Irregular betting patterns of 1.5 million on the race are being investigated.

The Jockey Club has banned Mr Fallon for 21 days for not riding out his horse to the finish and ordered an inquiry.

Background: Law Society finals at London College of Law in 1973, articled to City firm Elborne Mitchell.

Qualified in 1976, but gave up practising certificate to become licensed bookmaker in 1980.

Back to the law in 1990 at Reid Minty, then moved to Ralph Davis in 1996 as a partner.

Route to the case: Introduced to Mr Fallon by trainer Linda Ramsden, then acted for him on a number of occasions, including pulling another jockey off his horse in 1994, and being sacked in 1999 by trainer Henry Cecil after being accused of having an affair with his wife - Mr Fallon denied any involvement.

Thoughts on the case: 'Mr Fallon believed he was speaking to members of the public, and gave his views on the chances of the horses he was riding, based on external factors.

No money changed hands - which even the News of the World admits - and the way he rode was not influenced.

I have insisted that the Jockey Club demands full disclosure from the News of the World of all their tapes [to check the legality of their creation].'

Dealing with the media: 'As a lawyer, I find that journalists do normally do what they say they will, for example if you tell them that something is off the record.

But it is very different when they are talking to clients - they think they can get away with it.'
