Neither Compagnon nor Cubitt founder and managing partner Simon Brocklebank-Fowler would comment.
It is thought Compagnon was unhappy at the exit of co-head of IR Noga Villalon. The Cubitt founding partner left just a few months
after Compagnon's arrival (PRWeek, 1 April 2005).
Compagnon absorbed Villalon's duties, although Brocklebank-Fowler said last month that he had been sharing investor relations
responsibility with Compagnon as co-head of IR.
After Villalon's departure Brocklebank-Fowler stepped back from the day-to-day running of Cubitt in favour of Gareth Thompson, who took on the new role of chief operating officer. Thompson, who joined in January last year, has since left the agency. He is a former JP Morgan Funds sales and marketing director.
Prior to joining Cubitt, IR veteran Compagnon spent 20 years at the New York, Paris and London offices of Taylor Rafferty.
Although his precise plans are not known, it is thought unlikely that he will start his own agency.
Last month Cubitt moved to boost its financial communications capacity with the acquisition of Beattie Communications' City arm
Beattie Financial (PRWeek, 9 December 2005).
