The only banks who currently offer bank accounts to undischarged bankrupts are Barclays, the Co-op (I can highly recommend them) and Think Banking (I remembered Andy!). Other banks may allow you to keep an existing bank account with them, but each case is different.
BTW once you are bankrupt (and once you are discharged) you have to declare this if you are asked. The bank may credit check you and find out that you are / have been bankrupt. I would say don't even think of withholding the information - it's not worth the hassle and could land you in trouble.
Yesterday is history, tomorrow is a mystery, today is the present - a gift to make the most of.
