The Labour leader said it is inexcusable that little has been done to accelerate the issue – just over two years after the EU referendum vote in June 2016.
Mr Corbyn said: “It looks dangerously like (there will be a no deal outcome) because this government has two years to negotiate, two years to at least set out what its position is and they haven’t even produced a white paper, and apparently they are only going to do that after the Cabinet’s weekend in Chequers this weekend.
“This is getting quite ridiculous. We’re looking at July 2018 and the leaving date is March 2019, and they still haven’t produced a white paper.”
He added: “This Government has had two years, made no progress at all and keeps on threatening to do special deals with Trump or somebody else, which would undermine what is almost half of all our trade.”
Speaking later on Friday at a rally in Livingston, West Lothian, he added: “A white paper after two years and it’s only going to be produced after she’s hosted a pyjama party for the cabinet in Chequers next weekend.”
He said his party would provide extra funding for the health service and that the Welsh Labour Government has increased its funding by five percent, urging the Scottish Government to follow suit.
Mr Leonard said: “There’s no getting away from the fact that the NHS is massively under-resourced and under-funded, and we’ve got to face up as society and understand that we may have to look at taxation.”
He suggested a wealth tax is being considered as well as income tax, highlighting figures showing a forecast funding gap of more than £150 million during this financial year across Scottish health boards.
The Scottish party leader added: “We need to understand there is a funding crisis at the heart of the NHS and the SNP are too timid to tackle it.”
