Following Dominic Cummings’ latest grenade/intervention yesterday, a former Special Adviser to the Prime Minister has added his voice to criticism of the No. 10 operation. Sean Worth, who spent two years advising Dave, writes this morning that “Downing Street lacks grip, direction and calibre” and that “beneath the theatre” of Cummings’ attack “is a kernel of truth”.

“It’s certainly the case that Number 10 hasn’t given the machinery of government anything like the political steer of either the Blair or Thatcher administrations, for example.”

Dr. Worth adds that the current model of coalition is to blame, arguing it has been “tested to absolute bankruptcy“. He concludes:

“Forming a coalition in 2010 that would share power on every front of decision-making will, I believe, come to be viewed as a serious mistake – one not to be repeated if we end up with another coalition next May.”

This is becoming a theme…
