Mark Tucker has reportedly completed his first serious task after taking over as chairman of HSBC Holdings.

Tucker, who took over the post from Douglas Flint, has found a replacement for chief executive Stuart Gulliver, who retires next year. The bank is now awaiting approval for its chosen candidate from the Bank of England's Prudential Regulation Authority, according to the Financial Times (paywall).

Tucker, the former head of Asian insurer AIA and the first outsider appointed as HSBC chairman in the lender's history, has apparently gone with HSBC tradition by promoting someone from within the bank.

The current head of retail banking and wealth management, John Flint, (pictured) is said to be the leading candidate to be the next chief executive. An announcement is expected in the next few weeks.

«It's pretty obvious that it would be an internal candidate, given they have appointed an external chairman. It makes sense that it would be [John Flint],» said one of 10 top shareholders who recently met with Tucker, according to the Financial Times report.
