Brexiteers reminded the Labour politician of his responsibilities to serve London as its mayor after he released a damning study suggesting a Brexit no deal could see the UK economy lose £54billion by 2030.
The taxpayer-funded report was written by Cambridge Econometrics, run by Jeremy Corbyn’s economic guru Richard Murphy,
Daniel Lacalle, a chief economist, mocked Mr Khan tweeting: “Estimates based on nothing, and proven wrong so far. What figure do we give? One million, No one will believe it, Say 500k then. Nice round number
Ukip’s Peter Whittle wrote on Twitter: “So with a crisis in violent crime in London, @MayorofLondon produces this?
“An anti-Brexit ‘report’ to keep Project Fear going.
“This was the man who also claimed half a million London jobs depended on us being in the EU.
In a hefty statement, GLA Conservative Leader; Gareth Bacon said: “This is merely scaremongering and speculation.”
He said: “Sadiq Khan, a well-known Remainer and advocate of Project Fear, has simply produced a continuation of his widely publicised anti-Brexit views.
“This is hardly a surprise, particularly given that most of the authors of this ‘independent’ report are already on record as vehemently opposing Brexit.”
Keith Prince, London Assembly Member, branded it his report a “waste of time and taxpayers’ money”.
He said: “1st September 2015: Sadiq Khan promises to do everything possible to cut stop and search.
“10th January 2018: “Stop and Search Blitz.”
“A welcome u-turn, but yet another example of @SadiqKhan’s appalling judgement.”
Julian Jessop, chief economist and Head of the Brexit Unit at the Institute of Economic Affairs, said the report was “fundamentally flawed”.
Writing his reasons, he said: “The potential impact on investment out until 2030 is largely based on simple extrapolations of the trend since the referendum – a relatively short period of exceptional uncertainty.
“The potential benefits of Brexit are ignored. For example, ‘this study does not consider that, following Brexit, the UK might negotiate more preferential trade agreements with non-EU countries than the existing deals.”
International Trade Secretary Liam Fox called the report into the impact of Brexit “anything other than cataclysmic”.
Dr Fox said the findings suggested the UK would lose half as much of the market share as was forecast before the EU referendum in the event of a no-deal Brexit.
He also told MPs that Britain would not necessarily lose any of its market share with the EU, given the UK’s desire to reach an open agreement with the bloc.
Research for the mayor of London warned of a “lost decade” of significantly lower growth.
The country could have 500,000 fewer jobs in the worst-case scenario and nearly £50 billion less investment by 2030.
In London alone, there could be 87,000 fewer jobs and the capital’s economic output coud be 2 per cemt lower by 2030 than predicted under the status quo, it was warned.
Mr Khan said: “This independent analysis reveals the potential economic risks – and human costs – at stake in the negotiations.
“If the Government continue to mishandle the negotiations we could be heading for a lost decade of lower growth and lower employment.
“The analysis concludes that the harder the Brexit we end up with, the bigger the potential impact on jobs, growth and living standards.
“Ministers are fast running out of time to turn the negotiations around.
