Prudential is canvassing support from shareholders to stave off calls for chief executive Tidjane Thiam to go following his failed bid for AIA.
Attempts to rally shareholders are part of a fightback against demands from some quarters for Prudential's top management to resign, after the collapse of the $35.5bn (€29bn) takeover deal for the Asian business of AIG.
Chief executive Thiam and chairman Harvey McGrath will face a public grilling over the insurer's failed bid for AIA and on their strategy for the future at the annual shareholders' meeting on Monday, according to the Financial Times.
Prudential is set to make a £450m loss on the failed acquisition, which includes a £152.6m break fee to AIG.
Thiam and other senior executives have been heavily criticised over events of recent days and face demands for resignations, according to people close to the group.
Pru issued a statement on Thursday confirming its agreement with AIG had been terminated.
Managing director of Neptune Robin Geffen had been trying to rally support for a vote of no-confidence in Thiam during the Prudential chief executive's botched attempt to acquire AIA.
Neptune owns around £50m of Prudential share, and Geffen organised an action group to secure the votes of 20% of shareholders against the transaction.
F&C, which owns just under 0.7% of the insurer, also said it would vote down the deal.
