The ex-Pillsbury Winthrop partner at the centre of an acrimonious public row over an aborted move to Latham & Watkins has filed a multi-million dollar claim against his former firm.

Frode Jensen filed a defamation $45m (£29m) suit against Pillsburys on Tuesday (8 October) in the Connecticut Superior Court claiming his old firm acted “in a disgraceful and repugnant campaign to disseminated false and defamatory information”, according to US press reports.
