Johnson stated that the Spring Statement was inadequate given the great challenges at hand, and that concrete proposals for funding needed to arrive quickly.
British Prime Minister Theresa May stressed on Tuesday that parliament's approval of the withdrawal agreement she has reached with Brussels will deliver a fiscal "Brexit dividend".
He warned: "Leaving with no deal would mean significant disruption in the short and medium-term and a smaller, less prosperous economy in the long-term, than if we leave with a deal".
"This is up from £15.4 billion in October, as the fiscal costs of the temporary near-term cyclical weakness of the economy have been swamped by the fiscal gains from higher income tax and lower debt interest spending". "That is not what the British people voted for in June 2016".More news: Browns RB Hunt suspended 8 games

For, despite Mr Hammond's bullishness about the robust of the economy compared to other G7 countries, the Chancellor could not gloss over the fact that economic growth this year has been reduced to 1.2 per cent - a significant downgrade - and that future improvements to the funding of schools and other key services, frequently and vociferously demanded by MPs of all parties, are contingent on a Brexit resolution of sorts.
While Brexit matters, it is not the only thing that matters, he said.
The chancellor said he intends to launch a full three-year Spending Review "before the summer recess" in order "to be concluded alongside an Autumn Budget".More news: Carphone Warehouse fined £29m for insurance mis-selling
However, Britain's independent budget forecasters said nearly half of Hammond's fiscal headroom might be lost, depending on how official statisticians treat student loans in the public accounts.
But the Northern Ireland Chamber of Commerce and Industry said the statement had "little to offer, especially with regards to Northern Ireland".
"NI Chamber is fully supportive of the Derry/Londonderry City Deal and we hope this gets over the line soon".
The chancellor vowed to free up the cash to help end austerity in a "deal dividend", but warned that a disorderly Brexit would deal a "significant" blow to economic activity in the short term.More news: Anthony Davis Trade Rumors: Pelicans Refuse To Deal With Lakers
"This is extremely concerning, especially for Northern Ireland, which already has productivity levels amongst the worst in Europe and the lowest across the United Kingdom regions". The Chancellor said company audit committees would be required to review payment practices, and report on them in annual accounts.
