Barclays has appointed a former chief executive of asset manager Legal & General as a non-executive director, as the UK bank attempts to toughen up its financial oversight in the wake of the Libor-fixing scandal.

Tim Breedon will join the bank from November 1, having ended his role as chief executive of the UK's largest asset manager in June, when he also stepped down from the board. Breedon had been with the firm since 1987, becoming group director for investments in 2002 and chief executive in January 2006.
