Portugal workers

By the BBC's Alison Roberts in Lisbon

A Portuguese government study has concluded that the country will need to bring in 22,000 foreign workers by the end of this year to help meet its labour needs.
The study is the first produced by the Institute of Employment under a law that in January laid the basis for Portugal's first ever immigration policy.
Long a country of emigration, Portugal saw the tide turn after it entered the European Union, which has transformed its economy.
Labour shortages, a booming construction sector and the authorities' reputation for turning a blind eye to illegal employment have accelerated the process, attracting tens of thousands of migrants from eastern Europe.
