Of course this is a bit different but if I were doing a big wire transfer I'd probably call Barclay's Bank and verify who the account holder was before making the transaction and when they gave me a different name, end of deal.
I believe that the case will hinge on due dilligence, or lack of the same, by Barclays when opening the accounts. UK banks are obliged to make customers jump through hoops to open an account.
There is a long history of cases of this type and banks have been found liable in the past if it was found that they failed to show proper dilligence in managing an account. (A lot easier in the days when a manager could know all his customers but the courts then expected correspondingly more care)
