The former Newsnight presenter was recorded asking the former Labour leader “Are you okay, Ed?” after interviewing him on a Channel 4 election programme in March.

Paxman, who described the 2015 election campaign as “monumentally dull”, told a Royal Television Society lunch today that he also asked Tory leader David Cameron if he was “okay”.
