The AA's IT director has left the company following its £6.5bn merger with Saga, the insurance provider.
Trevor Didcock will be replaced by Jim Cameron, the IT director of Saga, who will now act as group IT director over AA and Saga.
AA and Saga will continue to trade as separate companies, although a group management team will oversee areas such as finance, HR and IT, a spokeswoman said.
The announcement comes a week after the EC commission approved the sale of the AA, valued at £3.3bn, to Saga's private equity owners, Charterhouse.
Didcock joined the AA in 2004, six months before the breakdown service was purchased by private equity group CVC Capital Partners and Permira for £1.7bn.
While at the AA, he was responsible for the company establishing its own independent IT infrastructure. Before he joined the AA, Didcock was IT director at the RAC and before that, he was at confectioner Mars.
A study commissioned by the GMB union accused the AA of under-investing in new laptops for patrols. The AA categorically refuted the claims made by the GMB's report and said that £37m had been invested in IT infrastructure over the past three years.
A spokeswoman for the AA said on Didcok's departure that the company would continue to make significant investments in IT systems in order to improve services for customers.
