Transport Secretary Grant Shapps appeared to take a swipe at former Chancellor Rishi Sunak as he launched his Conservative Party leadership bid.
Boris Johnson has formally stepped down as Prime Minister, prompting a leadership election - the timeline of which will be announced next week.
Seeking to present himself as a candidate with a track record of loyalty, Mr Shapps said he would not have started planning a campaign "behind Boris Johnson's back" - possibly a reference to the speculation that Sunak has been planning his bid for a long time.
