Whitehall thinktank says it is unfeasible to fully create and implement a new immigration policy by the end of the two-year article 50 deadline
European Union citizens will be free to come to the UK for several years after Brexit despite repeated promises from leave campaigners that restrictions would be swiftly introduced, a Whitehall thinktank has found.
A report released on Thursday by the Institute for Government (IfG) warns ministers it will be unfeasible to create a new immigration system by April 2019 at the end of the two-year deadline when Britain plans to leave the EU.
An end to EU immigration was a major concern among leave voters and forms a key part of Theresa Mays negotiating priorities. During the referendum campaign, David Davis now Brexit secretary said Britain must end its disastrous immigration policy.
The scale of the administrative challenge is too great and the current immigration system should be kept until a replacement is ready to avoid disruptive changes to labour markets, the think tank has concluded.
It also found the current process for registering EU nationals was not fit for purpose and the Home Office could require up to 5,000 extra civil servants to cope with large numbers of applications and appeals.
The report comes a month after May angered some Brexit campaigners after conceding that there might have to be an implementation phase on the free movement of people once an exit deal has been struck.
Jill Rutter, the institutes Brexit programme director, said: The political imperative for change in immigration is significant, but so is the administrative challenge. The scale of the task creating a new immigration system is huge and it is critical that government gets it right.
The current process for dealing with permanent residence applications from EU nationals is not fit for purpose, as the government itself acknowledged. It needs to be streamlined as a matter of urgency and as a first step towards a new post-Brexit system.
Under article 50, any country that invokes the provision has two years to negotiate a settlement before it leaves. The treaty clause has never been used before and legal and political opinions are split on how exactly secession would take place.
Freedom of movement is one of the four pledges enshrined in the Treaty of the European Union, giving citizens of member states the right to move freely within the EU to seek work.
Thursdays report points out that the scale of the task makes successful implementation of a new immigration regime by April 2019 unfeasible for the government, employers, landlords and providers of public services who rely on the system and support its functioning.
Joe Owen, the IfGs researcher and report author, said: Brexit is an opportunity to design an immigration system that is more effective for the country and less burdensome for employers.
Its important that the government avoids making multiple changes and introducing unnecessary disruption and confusion.
To provide stability, we should continue with the existing migration system until the new one is ready.
Business leaders urged the government to stand firm rather than create a raft of new rules, which would be a bureaucratic nightmare for firms.
Samus Nevin, head of employment and skills policy at the Institute of Directors, said: What employers dont want is the instability of having to waste a great deal of time and effort learning to navigate multiple rounds of changes and new rules. That would create a bureaucratic nightmare for recruiters, especially smaller firms.
If somethings worth doing its worth doing right, so if that means continuing with current arrangements for a period of a few years until the Home Office can put the infrastructure in place to implement a new system, then it will be worth the wait.
