The claim was made by Paris based writer Anne-Elisabeth Moutet, who is published by both French and British publications. Mr Macron addressed Brexit during his New Year address to the French nation.
In an incendiary move he claimed the ‘Leave’ vote had been “born of many lies and false promises”.
At 23:00 on December 31 Britain exited the EU Brexit transition period and regained its status as a fully independent trading nation.
It now trades with the EU on the terms of an agreement Boris Johnson reached with European leaders on December 24, which was swiftly pushed through Parliament.
In his address Mr Macron insisted he had “protected our interests, our industries, our fishermen and our European unity”.
He added France’s sovereignty lies “in Europe” but said the British would remain “our neighbours, friends and allies”.
Writing in the Daily Telegraph Ms Moutet explained how the reaction from the “European establishment” had turned her into a Brexiteer.
She said: “I’ve always seen Brexit as a bit of an own goal.
“It seemed to me that when you’re the second or third-largest economy in the bloc, you can push things your way from the inside.

“I also saw the benefit of having a truly free-trading country, which also happened to be France’s only serious military partner, in the EU mix.
“But for the first time since this all started I’ve become so angry with the EU (and with my own country ’s leaders) that my heart now supports the Brexiteers.
“After one too many TV debates when, just because I tried to explain the Leavers’ motivations, I got talked down by assorted representatives of the European establishment, each more dismissive and self-satisfied than the other, the current omnishambles of the EU’s health policy power grab was the last straw.”
Ms Moutet also said the European Union’s botched coronavirus vaccine policy had helped turn her against the block.
Whilst the UK administered its first vaccines on December 8 European countries had to wait for several more weeks as Brussels attempted to coordinate an EU vaccination policy.
Many European countries also have a shortage of vaccines as they placed bets on vaccines which how look unlikely to be completed for months, at the very earliest.
Ms Moulet explained: “Health remains broadly outside the purview of the EU – or at least it does for now.
“The collective purchasing of vaccines by the 27 was intended to show how much more efficient the EU would be than individual nations.
“But, as was superbly uncovered by the German news magazine Der Spiegel, this was one case of mission creep too far.
“While Britain started to vaccinate in droves, the EU’s vaccination campaign was delayed for weeks because they chose to buy from six suppliers equal amounts of doses even though three of those – national champions like France’s Sanofi – are years away from producing a vaccine.”
Consequently she argued Britain needs the EU “like a fish needs a bicycle”.
Whilst Britain formally left the EU at the end of January 2020 it remained in a Brexit transition period until the end of December.
During this time the UK still had to implement many EU rules and pay into the Brussels budget.
Had no new agreement been reached Britain and the EU would have traded on World Trade Organisation terms.
