Why are the most extreme Tory MPs so influential? The European Research Group pressed for the hardest of Brexits, and the government gave it what it wanted. A similar faction, the Covid Recovery Group, lobbied for the removal of public health measures, and again succeeded. Now the Net Zero Scrutiny Group, featuring some of the same characters, demands the abandonment of effective climate policy, and is clearly gaining ground.
Why? Because the Conservative party has long been drawn towards its extremes. It is pulled this way by the gravitational force of dirty money. This is a result of the pollution paradox. The paradox proposes that the most antisocial commercial interests have the greatest incentive to buy political favour, otherwise they would be regulated out of existence. So politics comes to be dominated by them.
