There’ll be claims that this is yet another example of the BBC’s inability to hold on to its talent. Andrew Neil and Andrew Marr have already left (the latter for LBC, where he may soon be bumping into Emily and John in the lift). Marr said he was “keen to get my own voice back”, away from the BBC’s impartiality drive. That may be, if not a factor in the pair’s decision, at least an added bonus.
