Groupama Insurances director of motor underwriting Jack Brownhill is to retire at the end of the year after 40 years' service.
Brownhill first joined the UK Group in 1964 and has risen through the ranks, said Groupama.
His dedication to the industry was officially recognised when he received the British Insurance Awards for Underwriter of the Year in 2002.
He also collected consecutive Insurance Day awards in 2002 and 2003 in recognition of the company's fleet and private car underwriting respectively.
Brownhill will be succeeded by Andrew Goldby, the company said.
