Institutional investors in AMP have raised "serious concerns" about risks to members' retirement savings posed by the company's "failure to foster" gender diversity and social inclusion, two weeks after the besieged wealth giant promoted an executive accused of sexual harassment.

Healthcare industry superannuation fund HESTA – which manages $53 billion on behalf of 850,000 members, 80 per cent of whom are women – met with AMP chairman David Murray directly in an attempt to hold the wealth manager's board to account on its response to the internal and public furore over its promotion of Boe Pahari as boss of AMP Capital.
