Up to a third of the AA's top management, includ-ing managing director of AA Personal Finance

Clare Salmon, could lose their jobs on completion of the takeover by CVC Capital Partners and Permira.

New head of the AA Tim Parker is expected to make an announcement over the next few days including details of the management shake-up.

A market source said: "Tim's track record shows he is fairly ruthless when it comes to taking over companies. When he moved in to run Kwik Fit, following the takeover by CVC, there were wholesale changes."

Completion of the £1.75bn deal to buy the AA is expected today following FSA approval earlier in the week.

Though no announcements have been made about changes in top management at the AA, sources reveal that Salmon's job has already been offered around the market.

A spokesman for the AA said: "The sale of the AA is going to plan and Clare continues in her role. No announcements have been made."
