Bradford and Bingley has commissioned a poll of its customers to find out their views on its conversion plans.
The poll comes at a time when predicted windfalls have fallen from £1,000 to £600 and has sparked claims that the poll was designed to whip up members support for conversion ahead of the vote on its mutual status in July.
The new poll includes questions such as “will the size of the windfall affect how you vote?”
It is predicted that if B&B floats it will now be worth just £2bn, meaning its three million members will get windfalls of about £600.
Save our Building Societies campaign co-ordinator Bob Goodall thinks B&B may be concerned that members do not want to convert. He says: “This poll could be designed to encourage more members to vote for conversion.”
