The 35-page report on the potential costs of Brexit to Germany said Britain’s departure from the EU risked “serious economic and stability relevant consequences; effects in particular on the real economy.”
The ministry officials calculated Berlin would have to pay an additional 4.5 billion euros (£3.8billion) a year into EU coffers as a result of Britain’s departure from the bloc.
To mitigate the cost, they floated the idea of charging Britain for access to the single market.
Angela Merkel’s government is facing a £4bn Brexit bill
The German leader had previously called Theresa May “deluded”
Focus quoted the officials as saying: “Such a future financial contribution should be used to alleviate the financial consequences of Brexit (reduction in EU spending or increase in payments for other member states).”
A Finance Ministry spokesman declined to comment on the Focus report.
Brexit would also put additional strain on German tax and customs officials as there would be new tax liabilities for products and services bought from British companies, the report said.
The report follows Angela Merkel softening her stance on the UK’s Brexit deal.
The chancellor admitted yesterday Germany “needs” Britain once it leaves the EU.
In a speech in Hamburg today, she said: “We will of course need, and want to have Britain as a good partner in the future.”
The German leader had previously called Theresa May “deluded” over Brexit negotiations.
