The Conservatives are considering cuts of up to £80 a week for sick and disabled claimants if they win the election, plans leaked to the BBC have revealed.

The leaked documents show that the Conservative party commissioned research into how much could be saved by measures including:

Taxing disability living allowance (DLA), personal independence payment (PIP) and attendance allowance (AA), saving a predicted £1.5 billion a year.

Abolishing contribution based ESA and JSA entirely, so that only claimants who pass a means test can claim these benefits. According to the BBC, DWP analysis suggests 30 per cent of claimants, over 300,000 families, would lose about £80 per week, saving a predicted £1.3bn a year. In fact, some families would lose more than £80 per week if these benefits were abolished.

Cutting the number of people getting carer’s allowance by 40 per cent by only awarding it to those eligible for universal credit (UC), saving a predicted £1bn.

Limiting child benefit to the first two children, eventually saving £1bn but very little in the short-term.

Other plans include replacing industrial injuries benefits with an insurance policy for employers, regional benefit caps and changes to council tax.

The Conservatives deny that these proposals are party policy.

A spokesperson for Iain Duncan Smith told the BBC that: “This is ill informed and inaccurate speculation.

“Officials spend a lot of time generating proposals - many not commissioned by politicians.

“It’s wrong and misleading to suggest that any of this is part of our plan.”

However, the Conservatives still refuse to say what benefits they will cut.
