Thank you. I will certainly ask the Minister to provide some clarity via a written statement. You're absolutely right that the whole point of having that policy of free prescriptions is to keep people well and to make sure that those who are employed are able to stay in employment. If we do have this disparity, I think you're quite right; you don't want to see that inconsistency or a postcode lottery, where you have some areas charging. So, I will certainly ask the health Minister to bring forward a written statement with that clarity.
