Obviously not a 'fake' recording then. 
"Ashworth says he was trying to 'psych out' Tories when he said Labour would lose in private call."
"Jonathan Ashworth is now saying that when he told his Tory activist friend that Labour was bound to lose the general election (see 11.44am), he was actually just trying to “psych out” the opposition. He told the BBC’s Politics Live he was speaking to Greig Baker, a Tory activist and old friend who runs a political intelligence agency. Ashworth went on":
"He was ringing me. I was talking to him. He was saying his sources at CCHQ say Labour’s doing well. I’m doing the old, what Alex Ferguson would do, football manager kind of thing, trying to psych him out, saying: ‘No, you’re going to win, don’t worry about it,’ because I know he’s an activist in Canterbury, I’m trying to make him complacent."
"Obviously I look a plonker now. I was a smart Alec - too clever by half."
"You’re going to say: ‘Well, you said this about Jeremy, you said that about the Labour party.’ Well, I’m deliberately throwing the Tory attack lines back at him to say this is what we’re getting."
