“The BBC’s Martha Kearney has had a steer. Here are two posts that she’s put up recently on Twitter.
Lab campaign source tells they think 310-320 for Cons; 280 for Lab. 71% turnout
Senior Tory tells me they have small overall majority.”

That sounds to me like someone is putting on a happy face. I'd bet Labor loses some down-ballot races they hadn't expected to lose. In other words, I'm guessing the Conservatives do better than expected, Labor worse.
That tweet in #23 apparently violates UK Election laws.
