1. The legal framework exists already to detect and punish tax evasion, which is illegal.
2. Tax avoidance is legal and therefore not susceptible of punishment without changing the law to close loopholes.
3. Shock, horror, a terrible revelation for left wingers. It is not solely Tories who avoid taxes. It is Corporations and rich people of every stripe and political persuasion.

4. I don't recall any such witch hunt being directed at New Labour, who signally failed to attempt a reduction in tax avoidance during their thirteen year opportunity, possibly because they too had both feet firmly in the trough as with the scandalous misuse of expense claims.

Try again lads, and maybe you might come up with something bad which is Tory only, but you haven't managed it yet.
