I believe that if Labour (or Labour & Lib Dems) had been in power these past seven years their policies/reforms would have been very nearly identical. And that should they be elected to office in June they would retain those policies/reforms. Why I'm so sure is that I can recall the Thatcher/Major years, and the proceeding Blair/Brown tenures when they undid absolutely nothing that the Tories introduced. Without being confrontational, can you tell me of any instance of memory failure?
Edit: I recall Blair restored union rights for GCHQ workers.
