The ways in which you build up a phrase, sentence, or paragraph are supposed to help, not hinder, the reader. Sometimes you wonder, especially in newspapers which are written in indecent haste for the next day, whether the rule is always being followed.

Surely, the logic of the word "refused" (a negative idea, but not syntactically) would require the next sentence to start with "So have the Tories...".
