Former Health Secretary Jeremy Hunt has said his ambition to lead the Tories has not "completely vanished" as Boris Johnson faces the threat of a challenge.
Hunt, who has also served as Foreign Secretary, insisted in an interview "it would take a lot to persuade me to put my hat into the ring".
The comments were interpreted as a sign that a challenge to the Prime Minister could be coming as he battles to maintain authority over allegations of rule-breaking parties in No 10.
