British Prime Minister Theresa May narrowly avoided a defeat in parliament at the hands of pro-EU lawmakers from her own party on Tuesday, fending off a rebellion that had threatened to deepen the crisis over her Brexit strategy.
The MP's partner, Esther McVey, is the welfare secretary.
Johnson, who was the figurehead of the Vote Leave campaign, warned the government not to "make the fatal mistake of underestimating the intelligence of the public", who he claimed would understand that the deal the prime minister is proposing is "Brexit in name only".

But if she won a confidence vote, she could not be challenged in this way again for another year.
Johnson insisted there was still time to adjust and that the country must do so because much was at stake.
Dismissing concerns from Brussels and Dublin over the Irish border, Mr Johnson called on the Prime Minister to return to the "glorious" plans she set out in a speech at Lancaster House a year ago - "a strong, independent self-governing Britain that is genuinely open to the world, not the miserable permanent limbo of Chequers".
"If we get distracted by individual amendments to individual pieces of legislation. then I think we get dragged into an unnecessary debate that wastes a lot of time and energy", Foreign Minister Simon Coveney told state broadcaster RTE.
