SRM Global Master Fund joined RAB Capital yesterday by publishing a letter to Northern Rock shareholders urging them to support the resolutions the two hedge funds have put down at a special meeting to be held by the beleaguered mortgage bank next week.

The two hedge funds, which hold more than 17 per cent of Northern Rock's shares, have demanded an extraordinary meeting to pass resolutions that would stop the board from issuing new shares, buying or selling assets, or making changes to the structure of the bank without explicit approval from shareholders.
