Credit Suisse’s Jamie Welch may not be as familiar a name in European circles as Luigi de Vecchi, the London-based global co-head of the investment banking department who is taking a break from the industry, but he boasts an impressive dealmaking record that includes working on the biggest buyout in history, and has a prominent profile within the corridors of the Swiss bank.

Energy banking specialist Welch, a 45-year-old Australian legal graduate from the Queensland University of Technology, who is set to move to London from New York to become head of the investment banking department for Europe, the Middle East and Africa, started his career as a solicitor and barrister with Minter Ellison in Melbourne in 1989. He then switched to Milbank, Tweed, Hadley & McCloy's New York team five years later.
