The Government does have estimates for the number of workers from Romania and Bulgaria who could come to the UK once restrictions are lifted - but it is currently refusing to tell the rest of us while it decides whether revealing the figures would be in the public interest.
The Department for Communities and Local Government has confirmed that the information exists.
But responding to a Freedom of Information request asking for the numbers, an official said: "Your request . . . raises complex public interest considerations which must be analysed before we can come to a decision" on whether to release the numbers.
