We don't have an advance copy of the Treasury's report, but some it has been leaked.
For now, we have just one question for the Treasury and for Mr Osborne:
If Brexit will be so cataclysmic, why did Mr Cameron say he'd campaign for Brexit if he didn't get his 'reforms' from the EU in January?
Those inconsequential changes made no difference so...
If the Treasury report were true,
neither Cameron nor Osborne could ever have campaigned for Brexit
and should have told us all this years ago.
It's increasingly impossible to take anything the Government says seriously.
STOP PRESS - Reactions start to come in:-
"If Osborne believes all that, did he REALLY mean it when he said he'd be ready to leave EU if UK didn't get renegotiation?" - Laura Kuenssberg, BBC Political Editor.
"He would never be allowed to produce something like this before a General Election and this is an abuse of the fair rules for a Referendum and he should be ashamed of himself." - Senior backbencher Bernard Jenkin MP, Chairman of Public Administration Select Committee, former Shadow Secretary of State for Defence, Shadow Regions Secretary, and Shadow Energy Minister.
"Few forecasts are right for 14 months, let alone 14 years. Such precision is spurious, and entirely unbelievable." - Lord Lamont, former Chancellor.
"The Prime Minister was one of the senior advisers working in the Treasury while John Major's government tried to keep this country in the EU's disastrous Exchange Rate Mechanism. The ERM destroyed jobs and caused misery for families across the country. The remainers were wrong then, and they are wrong now - people should not trust their judgement on the EU." - Rt Hon John Redwood, former Minister and senior backbencher.
As @George_Osborne must know, "The only function of economic forecasting is to make astrology look respectable." - Steve Baker MP.
