The all-party pharmacy group (APPG) is "surprised and disappointed" MPs will not consider the decriminalisation of dispensing errors before Christmas.
The APPG announced in October that changes to the law to create a legal defence from prosecution for pharmacy workers who make an inadvertant dispensing error were expected to be passed to MPs by December 25. But the Department of Health (DH) told C+D on Monday (December 7) that this timescale is incorrect.
The draft change to the law is still being cleared and is expected to be agreed in spring 2016, the DH stressed.
The APPG responded that it is "concerned about the time it has already taken to reach this point". "It is vital the DH pushes forward this reform with the urgency it deserves," APPG chair Sir Kevin Barron MP told C+D.
Mr Barron said the group had "welcomed" the DH consultation on the changes earlier this year, and stressed the "current situation compromises patient safety by discouraging error reporting".
"We will be raising this matter with ministers," he added.
In March, the APPG listed decriminalisation in its manifesto for the Conservative government's first 100 days in power. In September, Sir Kevin pledged to use his influence to ensure the necessary change to the law received support from MPs.
