A 'no-deal' Brexit would lead to labour shortages in the East, according to a report published today.
Cambridge would be the worst hit city in the country, according to think tank Centre for Cities, because more than a tenth of its workforce is made up of EU migrants (12%).
Peterborough (11%), Luton (8%) and Northampton (6%) are also in the top 10 for cities which rely on EU workers.
The think tank's report looks at the economic contribution of EU migrants in English and Welsh cities and how these places could be affected by the end of freedom of movement after Brexit.
It highlights that 70% of EU migrants choose to live in cities, bringing significant economic benefits.
EU migrants are more likely to be in work than UK-born residents of these cities (70% compared to 58%) and are more likely to have a degree (33% compared to 26%).
The report calls for the Government to extend freedom of movement for two years after March 2019 in the event of a ‘no deal’ scenario.
The report also claims that EU migration to English and Welsh cities has slumped since the referendum.
The Government insists there will not be a "cliff edge" when it comes to employing EU workers after Brexit - and future policy will take into account the economic impact.
