Can a LL deduct extra rent from deposit for after tenant has left property

Some conflicting opinions here, maybe not a straightforward area so to be clear the landlord exercised the break clause to end the tenancy early by giving the two months written notice and serving the section 21 alongside. A week before the end of the two months period the tenant said she would be remaining in the property for a further two weeks and paid the rent up until the day she moved out - after she moved out the landlord asked for the rest of the month to be paid / deducted from the deposit.

Either she's liable or she isn't. The fact that shelter suggested she should pursue the recovery of any money deducted for this through the small claims court has me wondering, would it come down to whether a judge thought she had acted reasonably or not.
