You are not quite correct in your assumption. A&L certainly suffered a share price meltdown and the Board agreed a sale to Santander, owner of Abbey. This sale was agreed in September by a majority of shareholders (well, actually the big investment Companies agreed and as they outvoted the small shareholders it went their way). Whether the share price meltdown was due more to short selling, rather than major failure of the A&L is not clear, but panic swept the Government who were desperate to avoid another Northern Rock so coerced the Board into bed with Santander.
So as A&L is now Spanish owned it can offer anything it likes to potential customers. Santander have stated they do not need any injection of money from the B of E so they will stay independent. A&L will remain a separate entity just as long as it suits Santander, so is likely to merge with Abbey within the year.
Bradford & Bingley have similarly been coerced into bed with Santander at the Government's request.
One could ask if the Spanish Company are donaters to the Labour Party.
