EU reforms: Poland warning on 'discriminatory measures'

David Cameron is visiting the Polish capital Warsaw on Friday, as part of his diplomatic offensive to garner support for EU reforms.

Ahead of his visit, the Polish Minister for European Affairs spoke to the BBC's Chris Morris.

Rafal Trzaskowski said that while Poland would consider what Mr Cameron had to say, any EU treaty change would be very difficult.

"The European Union needs Great Britain... but the discussion will not be easy. Introducing something that will clearly be discriminatory, that's a red line for Poland," he said, in a veiled reference to Mr Cameron's call for restrictions on migrants' benefits.
