He didn't "admit" it. He was forced into a corner where he could not deny it. Which make for much better viewing.
For a minute, QT looked very hostile to Reform. By which I mean they got the same forensic treatment everyone should get equally.
There definitely seems to be something in the water. I can' move for clickbait about Reform turning on Farage. It's odd that a piddling £5,000,000 could have caused such a stir.
