Litigation boutique Loble Solicitors has closed after its founder Steven Loble quit the firm to join Collyer Bristow.

Loble said the decision to close the firm came as regulation and administration became increasingly burdensome, diverting his attention from legal work.

Loble will join Collyer Bristow’s dispute resolution team, which he aims to grow in the international market, with a particular focus on the US. “Collyer Bristow is definitely in growth mode,” he added.

“Loble sparked widespread debate in 2005 about the extent to which legal advice is privileged when he acted for the US government in its efforts to have Lovells partner Andrew Foyle give evidence in the Department of Justice’s case against the tobacco industry.
