In relation to my last question, have they been right about Eastern Europeans?

The figures from the Office for National Statistics also showed that an upsurge in new arrivals from Romania and Bulgaria was already in full swing in 2013 as citizens of those countries got ready for Britain to throw open its labour market. Migration from the two countries was 23,000 in 2013, compared to just 9,000 the year before.

The number of national insurance numbers issued to Romanians in the year ending March 2014 was 47,000, UP by 29,000 on the year before.

Mr Farage said: "With under a year left to the general election the verdict is clear. David Cameron has broken his solemn promise to the British people on one of the most important political issues. And he has done so because he refuses to take back control of our borders in respect of more than 400 million people from more than two dozen countries on continental Europe.

"If people want to get both the volume and the quality of immigration under control then it is perfectly clear they should vote UKIP today.

"It is also clear that we are seeing a very significant surge in immigration into the British labour market from Romania and Bulgaria as well as a more general rise in EU immigration, just as I forecast. We simply cannot go on like this if we are to even begin the task of restoring the living standards and community cohesion available to millions of hard working British families. Enough's enough."

Given the ONS's credibility, is this not proof that UKIP are right?
