Liberal Democrat Leader Jo Swinson said: “Boris Johnson must stop ducking scrutiny. His cowardly behaviour shows why he simply isn’t fit to be prime minister. How can we expect Johnson to stand up to Trump or Putin if he won’t even agree to a half-hour interview with Andrew Neil? It’s bad enough that the voice of Remain has been excluded from today’s debate. But it’s even worse that right now Boris Johnson won’t be held properly to account for his lies and extreme Brexit plans.”
