Very, very weird, you say you've looked and looked and somehow didn't find the document on their party home page with 47 policy positions in it?
Do you want to go through these one by one?
How about setting up a new 1,000 person returns unit to support in the processing of asylum claimants and return those with no right to be here. That's one. There's 46 more. How about hiring 6,500 new teachers?
You can argue that you don't agree with their policy positions (I disagree with quite a few of them) or that they lack some details, or the funding is debatable, but to say they don't exist is just... not to put too fine a point on it... fucking asinine. They're there. Fucking read them. This is all that's wrong with the country today, if something isn't in the form of a three-word slogan or a Facebook meme it doesn't exist.
You say "at least the Tories are doing something", could have fooled me. What is it they are doing exactly? Just one example of an effective deployment of policy will do. Just one.
All this isn't even to mention that we're not even in an election season yet, so Labour have absolutely zero obligation to release a full manifesto - especially when the Conservatives have a habit of stealing all of their most popular policies.
Honestly, the level of discourse in politics is about as bad as it's ever been.
