You should contact the Driver and Vehicle Licensing Agency urgently for a duplicate. Failure to produce your driving licence will result in the matter being dealt with by the courts.
The answer is no. You would need to apply for a replacement and produce it as soon as possible. If you have been asked to produce other documents (such as insurance/MOT Certificate) then you should produce them and explain that you are waiting for a replacement licence and that you will produce it as soon as possible.
Any queries relating to driving licences which have been taken from a driver by a court in relation to endorsable offences should be directed to the Clerk of the District or Sheriff court whose area covers the location of the offence.
