LABOUR’S Ed Miliband tried to head off a challenge from right-wing parties yesterday with the public launch of a “fair” immigration policy drive in the seaside town of Great Yarmouth.

The opposition leader struck a different tone from boss-friendly Ukip’s anti-immigrant rhetoric by pledging a clampdown on rogue employers via new powers to prosecute over low wages and exploitation.

Undercutting local workers’ pay or conditions by exploiting migrant workers would become a criminal offence under a Labour government, he said.
