Conservative leadership challenger Matt Hancock has refused to rule out extending Britain's membership of the EU beyond October, but insisted that he could provide the EU with a time limit for the backstop that would pass through parliament.
The Health Minister said his counterparts who had promised to leave by 31 October – deal or no deal – made false promises because Parliament would block any absence of no deal.
He said the result would be a parliamentary election that would be a "disaster for my party and extremely damaging to the country".
Hancock claimed that his renegotiation plan was detailed, "unlike some other candidates," and that he would first reach an agreement with the Parliament, which included a temporary break to prove to the EU27 that it could happen. He would then resume the negotiations.
The backstop is designed to ensure that there is no hard border between Northern Ireland and the Republic of Ireland, even though no formal agreement on trade and safety agreements can be reached.
Hancock told BBC Radio 4 that his plan was backed by David Lidington, the de facto Deputy Prime Minister, and that Brussels was open to change.
"It is perfectly deliverable until the 31st of October. Once you have a majority in the lower house, things can move quickly, "he said. "It's not about opening the entire revocation contract – it's about a time limit of the backstop." At the European Council in October, the EU has the opportunity to vote in favor of this addendum. "
Hancock repeatedly argued that Brussels would give in despite its previous position. "They almost suggested a time limit for the backstop, but they did not believe the prime minister would be able to get them through the lower house." That's why it's important that you show that you can do it, "he said.
Three more senior executives will launch their campaigns Tuesday: Rory Stewart, Andrea Leadsom and Mark Harper. The last two, Boris Johnson and Sajid Javid, will start their elections on Wednesday before Tory's first round of election on Thursday.
Leadsom, the former head of the House, will present herself as an "optimistic but realistic Brexitwoman" who would seek a "managed exit" from the EU, in which only minor side-agreements are made to prevent disruptions. Option explicitly excluded the EU ,
It will also promise to explain a climate emergency and a significant expansion of housing construction. "Our party has had success in the past, when it has ruled as an advocate of the people and has provided for freedom of choice and opportunities, a strong economy and global leadership," she said at her inauguration.
Harper, the former chief whip, is expected to be a clean skin that has not served in the Theresa May administration.
Although he has announced, as Michael Gove and Jeremy Hunt, not to rule out a Brexit without a deal, he will not be bound by the deadline of October 31. Afterwards, both Johnson and Dominic Raab have announced that Britain will leave with or without a deal.
In his introduction, Harper will say that a functioning government "can only be enforced by someone who has not been involved in what has been termed the 'worst example of cabinet discipline in British political history.
All 10 candidates participate in private voting. The first round will take place on Tuesday evening.
Overnight, Stewart accused some of his competitors – including Johnson, Javid, Raab, Gove and Hunt – of unrelenting £ 84bn in tax and donations, which he said could undermine the party's reputation.
"We just can not make any spending and tax reduction pledges we can not keep," he said. "We can not criticize Jeremy Corbyn for reckless donation promises if we do it ourselves. Cheap election bribes could cost us a lot. "
According to Stewart's campaign, Raab had pledged £ 38.2 billion in tax cuts, including raising the national insurance threshold, abolishing the stamp duty on residential property under £ 500,000 and lowering the property tax rate by 5 pence. Johnson's much-criticized plan to lower taxes for higher-paid people is said to have cost £ 14.1 billion.
Johnson's pledge came under fire from Gove, who said that "the one thing I will never do as Prime Minister is to use our tax and benefit systems to enable the wealthy to get another tax cut." He also took his lead start to annoy Johnson about his retirement from the 2016 competition.
On Tuesday, former Defense Secretary Michael Fallon, who supported Johnson, said he hoped the contest would not focus on celebrities.
"After that, we all have to work together, there are a lot of candidates, but I hope we can agree to make some of the personal things out of it, and in the end we all have to gather together, support the new Prime Minister and bring the party back together. "
