Labour Party Manifesto says UC will be reformed and redesigned immediately, providing dignity for those who cannot work. It says:
"Poverty in Britain is rising due to the Conservatives’ attempts to balance the books on the backs of the poorest. They have slashed social security over the last seven years, leaving more people in poverty, subject to a punitive sanctions regime, and reliant on food banks.
Labour will act immediately to end the worst excesses of the Conservative government’s changes. We will:
Scrap the punitive sanctions regime
Scrap the Bedroom Tax
Reinstate Housing Benefit for under-21s
Scrap cuts to Bereavement Support Payment.
The cuts to work allowances in Universal Credit (UC), and the decision to limit tax credit and UC payments to the first two children in a family, are an attack on low-income families and will increase child poverty. Labour will reform and redesign UC, ending six-week delays in payment and the ‘rape clause’."
There's more, much more, obviously, but it doesn't indicate a 'ploughing ahead with welfare austerity' at all. Quite the opposite.
