Err - I’m not sure if he is “performing” internationally. Certainly not as well as I had hoped. I still have images of him in a kitchen talking to Obama.
If he’s on painkillers, then I wish he’d admit it. He may lose the next election (I think that’s a foregone conclusion), but he may gain some respect for admitting a personal problem. It’s not like he hasn’t had troubles in the past, and has received the support from colleagues across the house. I am reminded of Charles Kennedy who admitted his alcoholism. He lost his job, but gained much more from coming clean.
The only problem with this is that if he isn’t on painkillers, and the story gains traction, then people will believe it regardless of the veracity of the claims.
