Some of Barclays’ biggest shareholders have threatened to vote against the bank’s planned £7bn capital raising unless it improves the terms of the deal that would leave it almost a third owned by Middle Eastern investors.

Those voicing dissent include Legal & General Investment Management, which owns more than 5 per cent of the bank, and Aviva Investors in the UK, with 1 per cent. They are pushing Barclays to come up with better terms for the bank’s long-term investors or face a revolt at the extraordinary meeting on November 24 to approve the deal.
