City bosses have warned the Government, the British economy could suffer a huge hit if banks don’t get what they want.
Threats that banks could also move jobs out of the UK have also been made.
The move by the financial sector has already provoke an angry backlash.
Richard Tice, co-chairman of the Leave Means Leave campaign, said: “This is a nonsense. It is just the banks, frankly, not dealing with the issue.

And together firms have drawn up a file of how a longer period to quit the bloc in stages could work.

“It focuses on the legal underpinning of a transitional arrangement.
“It’s a heavyweight legal piece of work.”
The Government is currently has not yet decided whether to make a clean break or support a gradual withdrawal.
But the latter is likely to spark a huge backlash among Britons who voted for Brexit.
The Treasury said in a statement finance minister Philip Hammond is closely listening to the financial sector’s views.
The document said: “Transitional arrangements are likely essential.
“This is important in order to avoid potential damage to the ‘real economy’ that is reliant upon uninterrupted access to financial services.”
The file also says the transitional deal should last a minimum of between three to five years.
The document also wants the ECJ, which override UK courts, would most likely have to govern any disagreements that arise during the transition.
The file said: “We well understand the political sensitivity to that proposition.”
