BHP shareholders yesterday urged the mining giant to raise its bid for Anglo American in yet another takeover battle gripping the City.
The Australian company is working on a revised offer after its mining rival last week rejected a £31billion approach.
Analysts said the bid needs to be more than £40billion to tempt Anglo to accept the deal.
A bidding war could push the valuation higher – with Glencore and Rio Tinto touted as firms that might swoop in with a rival offer.
Anglo was this weekend forced to defend chairman Stuart Chambers, who has overseen the sale of several blue-chip firms to foreign buyers, including Cambridge-based chip designer Arm.

BHP investors told Reuters they see value in an Anglo deal due to its copper assets.
The combined firm would be the world’s biggest copper producer at a time when demand for the metal has soared.
Shareholders said they are open to an increased bid to win over the London-listed firm’s board.
‘We potentially would be supportive if BHP raised their offer,’ one shareholder said.
An offer of more than £30 per share – valuing Anglo at more than £40billion – could ‘sway the decision’, analysts said.
And Jamie Maddock, energy analyst at Quilter Cheviot, suggested a rival bid could come from Rio Tinto and Glencore.
‘These industry giants have the capital and strategic interest to engage in such a significant transaction,’ he said.
