Aviva will cut 1,500 jobs by the end of 2017, the insurer has said.
The cuts amount to 5% of the company’s 31,500-strong workforce.
The news follows the British insurer’s £5.6bn ($8.5bn) planned acquisition of Friends Life.
“We appreciate that this news may be disconcerting for employees and we would look to ensure that any redundancies are kept to a minimum wherever possible, by using vacancies and natural turnover,” said a statement from Aviva.
“At this stage, no specific teams, roles or locations have been identified, as the proposed transaction has not completed,” the insurer added.
