Yes, lacklustre, boring speakers, perhaps with the exception of Lord Digby Jones and Boris Johnson. And that's coming from someone who would never vote Labour!
They really do have to stop navel gazing and wake up and smell the coffee.
The problem is, like it or not, modern politics is driven by media and unless you have a significant number of charismatic speakers that can grab attention, you are not going to survive.
Theresa May (probably) just about did enough. It's the most impressive I've seen her. But it wasn't exactly mind blowing.
