The boringly-named Legislative and Regulatory Reform Bill is in fact a very dangerous piece of legislation. It grants any minister the ability to amend, replace, or repeal existing legislation. The frightening thing is this: they would be able to make major changes to the law without Parliament being able to examine it properly, taking away the ability of Parliament to meaningfully represent the citizens of this country.
This is the preamble on the Save Parliament website.
You probably would have solved this by looking at the most frequent letters in the ciphertext, and knowing that ETAIN are the most common letters in english, with TH and HE the most common pairings of letters, you could have assigned best guess values to each letter in the ciphertext. Words would have begun to suggest themselves, after a few false starts you should have got a near complete text.
