Following the EU's enlargement by ten new member states in May 2004, several old members introduced restrictions on the free movement of labour, fearing the adverse effects of a widely predicted influx of migrants. Britain, along with Ireland and Sweden, chose to open its borders to migrants from Eastern Europe, expecting them to fill gaps in the labour market.
Under the so-called 2+3+2-year scheme allowed for by the Accession Treaty, each member state has the right to decide whether to keep or remove 'transitional restrictions' on the free movement of labour, which is a fundamental freedom of the EU. The member states now have until the end of April 2006 to decide on their approach to the issue.
The Commission has said that, based on its "rigorous analysis of facts," the free movement of labour is "economically rational" (see EurActiv 9 February 2006). Therefore the Commission has indicated that it would like to see the EU's old member states to open up their labour markets to the new member states' citizens.
To date, Finland, Portugal and Spain have declared their readiness to lift the barriers and allow new member state citizens unrestricted access to their labour markets.
From the outset, the citizens of Cyprus and Malta have been exempted from the 'transitional restrictions' - thus the barriers applied to migrants from eight new member states only (EU-8).
