We have the opportunity for input, such as the opportunity to present here or by other means. I don't think this is the kind of issue that lends itself to, or would be particularly well served by, a referendum. I think the issue is one for Parliament to deal with. I don't think you'd go from 3% up to a substantial percentage of people who'd really be keen and enthused and engaged, who'd study up on all the implications of it.
I personally don't favour a referendum.
