Nigel Farage has told ITV News there is a wider issue of benefits for EU workers in Britain that must be addressed.
The Ukip leader was responding to the Polish prime minister who criticised David Cameron for singling out his country over the issue of child benefit payments to children of EU migrants.
Mr Farage said that in-work benefits such as child benefit need to be taken in to account not just unemployment benefits.
He said: "Everybody weighs up the work the Poles do, the tax they pay against those that are claiming unemployment benefits. The hidden part of this debate in in-work benefits."
