Freshfields Bruckhaus Deringer has clinched a lucrative lead role on the €4.3bn (£3.02bn) buy-out of the world’s biggest travel bookings company, Amadeus, advising European private equity giant Cinven.

The transaction is a coup for Fresh-fields as it ranks as one of the firm’s biggest ever buy-out deals. Cinven splits its work between Ashurst and Freshfields, although Ashurst has usually acted on the bigger deals for the client.
