Ms Morgan made her remarks as she prepared to join a 60-strong group of Conservative MPs at the launch of a declaration of One Nation Values. Seven Tory Ministers including former Home Secretary Amber Rudd are ready to block Boris Johnson’s bid to take the UK out of the EU without a Brexit divorce deal if he becomes Conservative Party leader. Writing for the Conservative Home website, Ms Morgan said: “There is a long One Nation tradition in the Conservative Party.” The name itself is derived from a book written by Benjamin Disraeli, a Tory Prime Minister regarded by many as an outsider, she said. She added: “At a time when divisions in our country have never been more exposed, thanks in part to a referendum we called and still haven’t finally delivered on, the Conservative Party should be finding ways to renew the nation and address those divisions.
“I am clear that if the Party decides to focus its appeal mainly towards Brexit Party supporters, our demise will be swift.
“It is a party that thrives on exploiting divisions and wants to pursue a hard No Deal Brexit deliberately, and with no regard for the damaging consequences for the United Kingdom, including to the very fabric of our Union.
“Those who have always wanted a No Deal outcome to Brexit can at least say that is what they always preferred, and should be asked to explain what their version looks like and how they think they’d prepare for it.
“But there are those for whom a No Deal outcome is now a strategic leadership campaign choice.
“The One Nation caucus will be asking them to explain their decision to us, and how they’ve weighed up the risks involved to our nation.”
She added: “We believe it is right to be patriotic, and at the same time reject any forms of narrow nationalism.
“And that Global Britain is not a label just for a trade policy, but also accepts a responsibility to lead on global issues.
“That includes being clear that climate change is an emergency, and responding with proper urgency.
“We make a clear commitment to our public services, to ensuring that the market economy tackles unfair monopolies and argue that our economic policy must look at the financial health of the smallest grouping as well as the whole country.
“The health of our democracy and of our political parties matters to all of us.
“And neither is in good health at the moment. And that isn’t good for our nation.”
In a clear reference to the surging Brexit Party, led by former UKIP leader Mr Farage, she added: “The rise of other parties shouldn’t be ignored, but not should we be panicked into compromising on our core values.”
Speaking last week, the LSE’s Professor Tory Travers warned the Brexit Party represented an “existential risk” for the Conservatives.
He told Express.co.uk: He told Express.co.uk: “Nigel Farage is hoping a party created a few weeks ago can supplant one which dates back to the 18th century.
“The acid test will be whether a minority of Conservative MPs would decide to change their allegiance and join him.
“If that happened then I think the Conservative Party would be very badly damaged.
“There are a number of Conservative MPs who are under threat from the Brexit Party.”
