POLL tax riots-style “chaos” will result if the UK Government pushes on with the national Universal Credit roll out, Gordon Brown has warned.

The former prime minister branded the welfare reforms a “harmful and hated” experiment that will risk public disorder.

According to reports, millions of families could be left up to £200-a-month worse off when the new system is introduced in July.

In a speech at the University of Edinburgh, Brown will say that Universal Credit would remove £3 billion from the social security budget on top of child benefit cuts.

He is expected to call for the abandonment of Universal Credit, saying: “The safety net is not now the welfare state but charity and the lifeline for families in need is not social security but food banks.”

He will also warn five million children will be in poverty in 2022.
