Investment bank Dresdner Kleinwort Wasserstein could face a second wave of lawsuits from female employees in the firm’s London office alleging sex discrimination.
The news comes just two weeks after it emerged that six female bankers had filed a $1.4bn (£800m) class action against Dresdner in the US courts.
The women, who worked at Dresdner’s New York office, claim they were marginalised and denied promotion while male colleagues visited strip clubs and engaged in humiliating sexual banter.
Douglas Wigdor, the US attorney piloting their case, told the Observer there was a “high probability that we will file a separate action against Dresdner in the British court”.
Katherine Smith, one of the six original claimants, said that her boss described her as “the Pamela Anderson of trading” and that a glass ceiling at the bank denied her fair treatment and equal pay.
The German-owned bank has said it will “vigorously defend” the legal action by the New York women.
