Brexit could knock almost £800 off the annual wage of the country’s lowest-paid workers by the end of the decade, a major new report has found.
It comes after Treasury papers showed Britain could lose up to £66bn a year if it pursues the hard Brexit option – leaving the single market and EU customs union.
Theresa May’s Conservative conference speech signalling the UK will prioritise immigration over single market access in Brexit talks also sent confidence in pound sterling tumbling last week.
Hard Brexit’ will cost Britain £66 billion per year, claims controversial leaked Treasury report

Treasury coffers will take a £66 billion annual hit if Britain goes for a so-called hard Brexit, Cabinet ministers have been warned.
Leaked Government papers suggest leaving the single market and switching to World Trade Organisation (WTO) rules would cause GDP to fall by up to 9.5 per cent compared with if the country remained in the European Union.
The draft Cabinet committee paper seen by The Times is based on forecasts from the controversial study into the predicted impact of quitting the EU published by George Osborne in April during the referendum campaign.
Although the then chancellor faced widespread criticism over the report, the Treasury stands by its calculations, according to The Times.

The documents says: “The Treasury estimates that UK GDP would be between 5.4 per cent and 9.5 per cent of GDP lower after 15 years if we left the EU with no successor arrangement, with a central estimate of 7.5 per cent.”
It adds: “The net impact on public sector receipts – assuming no contributions to the EU and current receipts from the EU are replicated in full – would be a loss of between £38bn and £66bn per year after 15 years, driven by the smaller size of the economy.”
Brexit backers who have seen the documents told the newspaper the figures were unrealistic and claimed there was a push to “make leaving the single market look bad”.
But prominent Remain campaigners pushing for a “soft” Brexit that would keep Britain in the single market said the documents showed the “horrific damage” of leaving the trading bloc.
Conservative former minister Anna Soubry, a supporter of the Open Britain campaign, said: “The horrific damage of a hard Brexit is clear. Less tax revenue means less to invest in schools and hospitals, lower trade and investment means businesses and jobs at risk.
“This danger is precisely why Parliament must be involved in the principles to guide the Brexit negotiations.
“Britain will leave the EU, but we must do so in a way the protects our prosperity and reduces risk. The Government should now make clear the ‘WTO option’ isn’t on the table.”
Prime Minister Theresa May is facing growing pressure to allow MPs a vote on Brexit and the Government is also fighting a legal challenge over the use of royal prerogative to invoke Article 50, the process for leaving the EU.
Brexit Secretary David Davis told MPs the Government will “observe the constitutional and legal precedents” on giving MPs a vote on any treaty setting out Britain’s new relationship with the European Union.
Liberal Democrat leader Tim Farron said the leaked documents showed quitting the single market would wreck the economy.
“This is yet more proof that hard Brexit would be an act of sheer economic vandalism,” he said.
“The Liberal Democrats will stand up for Britain’s membership of the single market.
“We cannot stand by while this reckless, divisive and uncaring Conservative Government wrecks the UK economy.”
A Government spokesman said: “We want the best outcome for Britain. That means pursuing a bespoke arrangement which gives British companies the maximum freedom to trade with and operate in the single market, and enables us to decide for ourselves how we control immigration.”
