The Law Society and Solicitors Regulation Authority have said they will not act on an MP’s call in Parliament to investigate the alleged ‘active touting’ for business by libel law firms.

Denis MacShane (pictured), Labour MP for Rotherham, made the allegation in December. He told an adjournment debate on libel laws: ‘We need to end libel tourism. It would be helpful if the Law Society investigated the behaviour of firms such as Schilling & Lom and Carter-Ruck, because actively touting for business is a serious problem.’

Cameron Doley, managing partner of Carter-Ruck, said: ‘We do not cold call our clients. That is ambulance chasing of the worst sort. Our only form of communication is through our website, which is no different to any other of hundreds of law firms.’ He said he would write to MacShane. ‘There is a debate to be had about libel tourism, but it must be well-informed.’

Schillings declined to comment.

Law Society President Paul Marsh said: ‘It is perfectly legitimate for solicitors to draw potential clients’ attention to their legal rights provided they do not make unsolicited visits or phone calls.’

An SRA spokesman said: ‘Firms are entitled to highlight their areas of expertise in publicity, but not to make unsolicited phone calls or visits to members of the public to tout for business.’

MacShane declined to comment further.
