Shadow chancellor John McDonnell has said a Labour government would spent an additional £17 billion a year as he called for an "emergency budget" to alleviate the crisis in public services.
Mr McDonnell demanded Chancellor Philip Hammond hold an "emergency Budget" next week, as he urged his opposite number to make a "decisive" break with the "failed" Conservative policies of austerity.
Hammond will announce regulation changes to allow Britain's driverless auto industry, which the government estimates will be worth £28 billion by 2035, to get cars on the road within as little as three yeas, according to extracts of the budget released by his office on Sunday.
'For the first time - I've never seen this before - we've had the Government's adviser on tackling terrorism saying that that can not be tackled if we keep on cutting our police officers on the beat in our communities.
A Labour source said the £17 billion figure includes money to lift the public sector pay cap.
Treasury Minister Steve Barclay said: "Since Labour's recession we have turned our economy around by taking a balanced approach to public spending and backing businesses to create better, higher-paid jobs".
Labour's "grey book", which accompanied the party's General Election manifesto, set out £6.5 billion that "tax experts" advised could be raised by targeting tax evasion.
"This is a wealthy country, one of the richest in the world".
"Now is the time to borrow while interest rates are so low", he said.
'The costs would rack up and up, putting economic growth at risk and hitting ordinary working people in the pocket'.
"Even as they have been cutting public services to the bone, they have been offering huge giveaways to the mega-rich and giant corporations".
John McDonnell (Shadow #Labour Chancellor) should heed the words of Abraham Lincoln: You can not make a poor man rich, by making a rich man poor.
With nurses reliant on food banks and head teachers asking parents for donations to keep their schools open, he said Mr Hammond needed to take "strong, effective action" to deal with the problems Government policies had caused.
