Immigration minister James Brokenshire has said new figures showing net migration to Britain is at a record level are "deeply disappointing".
Net migration was an estimated 330,000 in the year to March - the highest level on record, according to the National Office of Statistics.
"These stark figures are deeply disappointing," said Mr Brokenshire.
"While these figures underline the challenges we need to meet to reduce net migration, they should also act as a further wake-up call for the EU. Current flows of people across Europe are on a scale we haven't seen since the end of the Second World War", he added.
One of the first Romanian migrants to arrive in the UK, after curbs preventing them from working were lifted, has spoken about his new life.
Levels of immigration into the UK could be about to hit their highest ever point, as the latest figures are due to be released this morning.
