Since you no longer an MOT Certificate and the details of all MOT failures are kept on a database which the Police will have instant access to, I think you would be unwise to drive the vehicle. You may get away with it, but as it has failed the MOT it is obviously unroadworthy. If you were involved in an accident, I would imagine your insurance company would not pay up if the found out the car had recently failed an MOT.
Please note that this is only my opinion and should not be seen as the "letter of the law"
