"Suspend disbelief" is probably the key phrase if you want to enjoy this colourful portrayal of a mysterious group hell bent of removing the prime minister. The plot twists get ever more absurd as the series goes on, and I've gone through more rigorous security checks at Greggs than the people who seem to be able to waltz in and out of Downing Street. However, Suranne Jones puts in a typically brilliant performance and Julie Deply is wonderfully sinister as the French President. The series kept me hooked in for a leisurely evening, which is more than most can these days.
