Mark Pritchard has followed up his grievances over Europe in The Telegraph today, claiming that David Cameron's weakness on Europe has forced him to resign from his job in the International Office.
Cameron's effect on the Tory Party has been profound. Among Conservative Party voters, members and activists, anti-EU sentiment remains commonplace. In fact, it's growing.
Yet because of the A-list, a highly controlled MEP selection procedure and so forth, it is the Tory Party itself which is leaving behind its Eurosceptic bedrock of support. It is the Tory Party itself that is now at odds with the likes of Mark Pritchard - he is the exception, the Cameroons are now the rule.
No longer does the Conservative Party talk of lower taxes, less government and the battle against a federal Europe. This Tory-led government is positively encouraging Euro fiscal union, even throwing billions of pounds of British taxpayers' money into the scheme to sustain the doomed Eurozone.
Some may say that 81 Tory MPs defying the whip and voting for an EU referendum is monumental. That depends. In terms of a rebellion, sure.
However, it also means that less than one in three Tories in the House of Commons wants the British people to even have a say on the issue. That surely demonstrates a huge commitment to Britain's continued support for the European Union, even as the Union is being exposed as flawed and ill-thought out like never before. The vast majority of Conservative MPs' loyalty lies with Cameron over the public.
Just as Tony Blair scourged true socialists and principled left-wingers from the Labour Party in the hunt for power, Cameron is doing the same to the Conservative Party (whilst failing to win the election). Anyone who stands for small-c conservative values isn't welcome anymore. The centre-ground doesn't welcome Eurosceptic conviction.
Within a Party that has a leadership process very heavily skewed towards the influence of its MPs, and a system of selecting MPs that relies strongly on Cameron's approval, it is hard to see a way forward for the likes of Mark Pritchard. I'm afraid the Tory Party has left him, just as it did Stuart Wheeler, Lord Hesketh, Lord Pearson of Rannoch, Lord Willoughby de Broke, Roger Helmer and so many more.
