I'm unclear who exactly you are expecting to defend the Tory party. They're bad. I don't like them. What they did is only legal since they and their kind make the laws. They maintain power by being marginally more electable than labour. The same Labour who had eleven MPs who signed a letter blaming NATO on the situation in Ukraine. They are realistically the two options our system allows. And we celebrate our Head of State overseeing this for 70 years.
And doing a few illegal things is hardly a framework for doing many illegal things - Blair's war in Iraq hardly created a common law framework for what he did.
