At best they are, as the Political Scrapbook blogger has pointed out, worked on a "Don't ask, don't tell!" policy. At worst these are nasty attempts to hoodwink the electorate and play shabby electoral games by cheating. I like to think the former, but it doesn't show the Tory leadership as statesmanlike material, and before some Conservative posters start bleating about Labour not being any better, is that the most feeble excuse you can have for a Party which aspires for government!
