The Lords have raised concerns relating to the on-trade and were considering making amendments to the draft as The Grocer went to press.
The Wine and Spirits Association said the drinks industry had expected it to get final approval last week, but any amendments to the Bill made by the Lords would have to be considered by the Commons. With Parliament due to go into recess in two weeks time, there is a danger that the Bill could be pushed into the October session.
The association's off-trade members have criticised the Bill for failing to address industry concerns.
A major objection is the requirement for off-licence chains to obtain the permission of whoever owns their premises to apply for a licence to sell alcohol.
