Theresa May’s conference speech — interrupted by coughing fits and with part of the set falling apart behind her — served as an unfortunate metaphor for her premiership and party. She is carrying on and in doing so, she demonstrates her resilience, but also her frailty. The horrified faces of cabinet members watching as her voice dried up on stage seemed to sum up their wider concerns about whether their party is in a fit state to see off Labour, so recently dismissed by them as a joke.
