Aviva, the FTSE-listed insurer, has unveiled a series of changes to its senior management following last month’s elevation of Maurice Tulloch to the top job.

Andy Briggs, the chief executive of Aviva’s UK insurance division — which accounted for over two-thirds of group profits in 2018 — is to leave the company. The former chief executive of pension provider Friends Life, he took charge of the combined UK business when Aviva acquired its rival in 2015.
