Mr Raab launched a scathing attack on the “dwindling” supporters of Project Fear, dismissing claims suggesting Brussels will not behave responsibly should Brexit talks result in a no deal.
Speaking to the Today programme ahead of a key speech, the Tory frontbencher said: “There is an irony in this debate because some of those promoting the worst scare stories around no deal, making the case at the eleventh hour to call off Brexit, are relying on the fact that they say or they assume the EU will behave in a vindictive way.
“I fear that’s the Achille’s heel of the latest incarnation of Project Fear by admittedly a rather small and dwindling number of those trying to frustrate Brexit.”
The Brexit Secretary insisted the UK will want to act as a “responsible European neighbour and partner” to the EU even if the British Government were to fail to strike a new deal with the bloc.
He continued: “We will continue to be a responsible European neighbour and partner. And I expect that will be the same position on the other side. We’ll all be bound by general international law.
“We’re striving for the best deal and I’m confident we can achieve it. But in the event of a no deal scenario, I’m confident cooler heads will prevail.”
Mr Raab also dismissed suggestions a no deal would have Britain run out of medicine stocks for the NHS, arguing the Government had a “long-standing set of arrangements” in place for disruption at the border in Calais.
He added: “With the pharmaceutical suppliers we have got three months of buffer stock already for over 200 medicines.”
During a speech to present a series of 25 technical notices on Thursday, Mr Raab said: “We set out clear steps that the public institutions, companies and people should take or consider taking in order to avoid or mitigate or manage the risk of any potential short-term disruption.
The Brexit Secretary explained there is already planning talks between the Bank of England and the European Central Bank for a no-deal scenario and called for talks to begin on data protection and between port authorities.
Under current plans, the reports will be published in batches, starting on Thursday and running through September.
The Government has not confirmed the subjects they cover but reports suggest they include subjects including aviation safety, civilian nuclear power, medical drugs, the rights of British citizens living in the EU, road haulage and fishing rights.
