Stewart, who is currently secretary of state for international development, has doubled down on his intention to step down from his job in the event of a Boris premiership.
The former Tory leadership candidate appeared on LBC to talk to James O'Brien, where he warned of Johnson’s “vagueness” as a danger to the country.
“I’m in a reflective moment. I’m within the last probably five, six days of my job,” he began.
Whilst he doesn’t regret saying that he won’t serve under Boris Johnson as prime minister, he does feel “sad about leaving DFID”.
One of the reasons I’m talking to you in a slightly exhausted, deflated way is that I’ve been in Congo, I’ve been in Kenya, I’ve just come back from New York trying to get money for Ebola, and trying to get climate under development so it’s a very odd time in one’s life [SIC]
It’s very unusual in a job to feel, in five days’ time my whole job goes, everything I’m doing goes, and then…
At this point Rob interjected, asking the conservative member what he would do if Boris asks him to stay in his role.
I have to say no. He’s advocating for a policy I can’t advocate for.
And then, the million pound question: How dangerous does Rory think Boris is?
After a long pause, Stewart eventually said:
I think the danger is the lack of detail, the lack of anything particular. It’s the sort of vagueness, the abstraction, the blandness of it that worries me.
I literally don’t know what happens on 31 October. I can’t plot his path.
Watch as @mrjamesob asks @RoryStewartUK "How dangerous do you think Boris Johnson is?" The silence was deafening...… https://t.co/EEU5BIJxDH
