Pascal Roux, a corporate finance and banking partner based at Richards Butler's Paris office, has become the first registered foreign lawyer to become a full partner at the City firm. Roux has been a local partner at the Paris office since 1995, having joined the firm a year previously. The firm has also promoted two French- and English-qualified lawyers, Lars Lewis and Clara Zerbib, to partnership at the Paris office. Richards Butler now has five partners, three full partners and two local partners, in its French office. Meanwhile the firm has made Hong Kong admiralty specialist Harry Hirst, who joined from Ince & Co earlier this year, a partner at the Hong Kong office. He will head up the firm's Hong Kong admiralty practice.
