Prudential chief executive Tidjane Thiam is pressing ahead with the faltering AIA deal, vowing to persuade shareholders to back the $35.5bn (£23.7bn) takeover of AIG's Asian business.
Thiam's determination to get the deal done comes despite growing shareholder unrest and regulatory upheavals, the Telegraph reports.
His assurances to investors come amid reports Prudential is in talks with AIG to restructure the deal, with proposals thought to include cutting the cash component by $2bn.
Last week the FSA stopped the insurer from proceeding with a record $21bn rights issue, which will part-fund the deal.
The regulator intervened over concerns the combined group would not have enough capital to withstand a future economic crisis.
