Secret tapes revealed Whitehall officials vowing to continue secretly splurging British money on EU projects including the EU army after Brexit.
According to The Sun, Cabinet Office security adviser Alastair Brockbank said the UK would continue to make “significant contributions” to Brussels defence and foreign policy projects after Brexit as they were plans “we are all interested in”.
Senior Brexit Department official Victoria Billing also likened the UK’s future deal with the EU to a KitKat in a bizarre metaphor.
Ms Billing seemed to suggest the deal would appeal to Leave voters on the surface – much like the teatime snack’s chocolatey coating – by giving the appearance of a harder Brexit.
However, like the wafer in the lunchbox favourite, there would be hidden political deals running through its centre.
She said: “On our our side, on foreign policy and defence, we are actually looking for something which I normally call a patchwork but someone yesterday called a KitKat which I rather liked.
“You have the kind of political framework cover and underneath you have a series of different agreements.”
Leading Brexiteer Jacob Rees-Mogg, who has previously lashed out against claims civil servants may be trying to undermine Brexit, demanded an inquiry into the tapes.
He said: “Former civil servants rounded on Brexiteers a few months ago and compared them to Nazis for questioning the traditions of the Civil Service and now we have civil servants appearing to brief against their country.
“The KitKat comment is a clear attempt to hoodwink voters.
“This looks like a clear attempt to fix the game and this must be formally investigated urgently.”
During the tapes, Mr Brockbank indicated the country may help to fund Jean-Claude Juncker’s plans for an EU army, known as the Permanent Structured Cooperation (PESCO).
He said: “We would see what we can contribute towards PESCO still.”
The civil servant is also said to have boasted that the plans would be kept secret from the UK public.
Mr Brockbank claimed the civil service “are negotiating the detail of that at the same time as we are discussing the political high-level fluffy bits that will go into any declaration that gets made public.”
Just last month, Mr Rees-Mogg was at the centre of an extraordinary row where he claimed civil servants were “fiddling the figures” on Brexit.
Mr Rees-Mogg claimed he heard a pro-EU think-tank boss saying Treasury officials had deliberately created an economic model to show anything other than staying in the customs union was “bad”.
The head of the Centre for European Reform, Charles Grant, rejected Mr Rees-Mogg’s account of his comments.
AnBrexit Minister Steve Baker later apologised to MPs for saying Mr Rees-Mogg’s account of the remarks by Mr Grant was “essentially correct”, after an audio recording of the meeting where Mr Baker had been speaking emerged.
