Pannick will not be appearing. He analyses and recommends lines to be followed. He can do the work after his second glass of port (Taylor’s 63) any evening.I'm very sceptical of date changes.
I'm aware Lord P probably has a big experienced team below him but I'd expect him to lead from the front and would assume that he's not sat at home on his backside waiting for this to start and is involved in other ongoing cases, his potential unavailability until the original date in November would render a 'quick start' unfeasible.
