Research-led broker Exane BNP Paribas has bid farewell to its long-standing head of research Vincent Laurencin, with deputy head Ben Spruntulis now running the unit.

Laurencin joined the Paris office of the French broker, a joint venture between Exane and BNP Paribas, as a media analyst in 2001 before moving to London in 2005. He left the business last Friday, according to a document filed with Companies House.
