Worker Registration Scheme to End
The Minister of State, Home Office (Baroness Neville-Jones)has confirmed that under the terms of the accession treaty, transitional measures relating to labour market access for nationals of member states that acceded on one May 2004 must end by 30 April 2011.
The worker registration scheme must cease to apply to nationals of those countries from that date. When the scheme ends they will enjoy the same rights as other European Union nationals in terms of their freedom to take employment in the United Kingdom.
Nationals of Bulgaria and Romania are not subject to the worker registration scheme and are instead subject to separate work authorisation requirements.
These restrictions will continue until 31 December 2011, and under EU law may, in the event of a serious disturbance to the labour market, be extended until 31 December 2013.
The Government will apply transitional controls as a matter of course in the future for all new EU member states.
