Speaking to the Sunday Morning with Trevor Phillips programme, the cabinet minister said the emergency legislation was "a tough but also proportionate measure".

The levelling up secretary indicated the government was open to making changes to the controversial draft law which faces a crucial first vote in the Commons on Tuesday, amid Conservative infighting.

Rishi Sunak brought forward the revamped plan in a bid to salvage his embattled Rwanda policy and deliver on his pledge to "stop the boats" after the Supreme Court ruled the policy unlawful.

Asked if there will be an early election if the bill does not pass the Commons, Mr Gove said: "No, we're not contemplating that because I'm confident that when people look at the legislation - and have a chance to reflect - that they will recognise that this is a tough but also proportionate measure.

"And of course, we will listen to opinion within the House of Commons."

Gove hits back at legal criticisms of proposed law from Tory right

It came as Mr Sunak was dealt a fresh blow by the Tory right, who have concluded his Rwanda bill is not "sufficiently watertight", and continue to leave the way open for illegal migrants to mount legal challenges in an attempt to stay in the UK.

The European Research Group believes the law's current wording will fail to achieve the aim of deporting those who make the Channel crossing to east Africa.

Conservative veteran Sir Bill Cash, who chaired the so-called "star chamber" behind the report, told The Sunday Telegraph he hopes it will help the government decide whether the bill needs further amendments.

More moderate Tories are weighing up whether they can support the plans amid concerns about compelling courts to find Rwanda is a "safe" country to send asylum seekers.

Jenrick reiterates new plan 'will not succeed'

Robert Jenrick, who resigned as immigration minister claiming the Rwanda bill was too weak, has confirmed he will not support it but told the BBC "we can fix this" - while raising the possibility he could abstain along with other opponents before trying to amend the legislation at a later stage.

He said: "I'm afraid it's very clear to all those people who really understand how this system operates that this bill will not succeed.

"I will always put the vital national interests of this country and the views and concerns of the British public above contested notions of international law."

In a thinly veiled sideswipe at Mr Sunak, he added: "We're sent to parliament to represent those people, the general public.

"We're not sent to parliament to be concerned about our reputations on the gilded international circuit."

'The toughest immigration legislation I've ever seen'

But Conservative former cabinet minister David Davis told Phillips he would be backing the bill.

He said: "The legislation is about the toughest immigration legislation I've ever seen in truth, and I actually think the prime minister is right that it can't go any further.

"He has to take a grip of this.

"I actually think this is a really hard piece of law... it's literally written on the decision of the Supreme Court."

He also had a dig at sacked home secretary Suella Braverman, who has been scathing of the approach being taken by Mr Sunak and the Home Office.

Mr Davis said: "It's a tough job... but it's all very well for her to come along and blame everybody else now.

"She's been in charge of this department for well over a year, and it didn't improve."

Warning colleagues against manoeuvring over a potential future leadership bid, he pointed out "people who trade off their own future against the future of the party always lose".

Labour keen on 'different plan that works'

Also appearing on Phillips' show, Labour frontbencher Liz Kendall said: "We want to use the money spent on Rwanda to have a different plan that actually works.

"The problem is we have seen the government spend months and months on a plan going around in circles."

However, despite the Tory divisions she predicted the bill would clear its first parliamentary hurdle "comfortably" as Conservative MPs wanted to avoid an election and risk losing their seats.

Meanwhile, anti-corruption campaigner Bill Browder has told the BBC the president of Rwanda "is like the Putin of Africa", as he called for the deportation policy to be "torn up".
