Brexiteer Commons Leader Andrea Leadsom quit over the PM’s bid to offer MPs the chance of a second EU referendum.
And seven other Cabinet ministers also told No10 they will not back Mrs May — a clear signal for her to step down.
But the PM refused to budge, with aides saying: “She is going nowhere until she gets Brexit done.”
Mrs May even refused a series of ministers’ demands for face-to-face talks, scrapping an appointment with Scottish Secretary David Mundell with ten minutes’ notice.
