Dr Julian Lewis: Trying to think ahead, does my hon. Friend [Tobias Ellwood] recognise that if his ingenious scheme were put into practice, the first reaction of the Taliban, who used to suppress the poppy crop when they were in power but now put themselves forward as the defender of the poppy farmers because they know that that rallies support for the insurgency, would be to offer a different sort of stick? Anyone who signed up to the scheme would face a different sort of eradication – personal eradication.
