Number 10 says no decision has yet been taken on whether to curb the rights of Romanians and Bulgarians to work in the UK once the countries join the EU.

Tony Blair's official spokeswoman said a decision would be made "at the appropriate time" later this year.

The European Commission will issue a report on Bulgaria and Romania in the autumn, which will indicate whether they should join the EU on 1 January or whether there should be a delay.

Existing EU member countries can block Romanians' and Bulgarians' work rights for up to seven years.
