LABOUR were warned to wake up to working-class alienation yesterday as polling showed poorer voters are most likely to turn to divisive Ukip policies in desperation for change. 

An Institute for Public Policy Research (IPPR) survey showed 68 per cent of white working-class people believed that Britain’s political system was not working for them — 9 per cent more than middle and upper-class voters. 

The YouGov poll of more than 3,500 people also found 13 per cent more working-class people support reducing immigration.
