Britain risks breaking European and domestic law if it pursues plans to make it difficult for new immigrants to get benefits, Bulgaria's foreign minister has told ITV News.
Nikolay Mladenov, who was educated in the UK, said Britain must uphold its reputation for offering fair education and health access for migrants.
His comments came after a think tank warned that around 50,000 people from Bulgaria and Romania will come to the UK every year once both countries join the EU at the start of 2014.
