The hon. Gentleman is moving on to discuss the broader issue of the environment, I think. A report last week from Zero Waste Scotland suggested that Scottish households spend £600 million a year just on packaging. We can do a lot in that direction. The Scottish Government have rightly taken a lead with the deposit return scheme. However, would it not be more sensible if all parts of the United Kingdom got together with a co-ordinated approach to a deposit return scheme that covered the length and breadth of these islands?
