The good news is that support for ReformUK (the company masquerading as a political party) may have peaked, but the bad news is this may be enough under first past the post to win the next election.
However, another three years of Local Govt. experience of Reform may sufficiently reduce support even among current supporters to make that more difficult, especially if the Left can organise themselves into a Popular Front to oppose ReformUK.
