Hardliners in the Belgian capital are determined to "punish" and "humiliate" Britain for daring to leave the bloc, the former Brexit secretary said. Meanwhile, Westminster MPs will be "tempted to try to prevent the British breaking off" by either postponing the exit day or diluting the Brexit. Raab said to those who want to demand an orderly Brexit to protect themselves against threats that were voiced on both sides of the English Channel in a Sunday Telegraph column next week.
"At the same time, we must continue to prepare for a WTO departure on 29 March.
"It is the responsibility of every government and will strengthen the government's bargaining position at this critical moment in the talks."
Mr. Raab served as Brexit Secretary from July 2018 to November 2018, but resigned to express concerns over the Theresa May contract.
He voted against the prime minister's deal when he came before the lower house states, even though he was involved in the negotiations, and warned that conditions were worse than staying in the EU.
Mr Raab also urged that Britain have a unilateral right to withdraw from the Irish border.
And last month, the former Brexit Secretary voted to replace Irish border management with "alternative regulations".
He said the result of the vote gave Ms. May a "clear mandate" to renegotiate her deal.
He said, "The biggest threat to a deal is now in the marginalization of hindering negotiations in the EU and the UK at their most sensitive moment."
Recognizing the challenges of a divorce treaty in the UK and Brussels, he said that MEPs who support an orderly exit should be willing to fight on two fronts.
He said: "There is a meeting with Commission officials and European leaders who want to punish Britain to show that leaving the EU is a humiliating experience.
"You have always misunderstood the mood in this country, but we will only make a deal if the pragmatists win the day.
Second, some MEPs will be tempted to thwart Brexit as the EU pulls out the negotiations for several weeks to test the UK's resolve.
"We should do our best to reach an acceptable agreement across the border, but we are ready to help if the EU rejects any reasonable compromise.
"If we look down the wrecks on either side of the canal, we'll have our best chance of completing the deal."
Mr. Raab's warning lasts 47 days until Brexit.
Theresa May asks MEPs for more time on Wednesday to make legally binding changes to the Irish border.
However, the EU has insisted that it will not agree to changes to the resignation agreement.
MEPs will have another opportunity this month to vote on their deal. Until February 26, a second "meaningful vote" will take place.
Ms. May was accused of shutting down the clock by keeping the vote so close to the issue date of March 29.
Some MPs fear that their goal is ultimately to force them to support their deal to avoid a no-deal Brexit.
