David Cameron has said that "no recipients will lose out, unless their circumstances change" and that "the money that is going into disability benefit will not go down under universal credit; it will go up".
Highlighting the Government's decision to focus "on the most disabled", the Prime Minister said they had chosen to "increase the amount that we give to the most severely disabled children, and there will be a new lower amount for less disabled people".
Mr Cameron's statement appears at odds with the findings of the report, which argued that 450,000 disabled people "could stand to lose out under Universal Credit".
Disabled people, those with long-term conditions and their families are already at risk of hardship and face massive barriers to getting into work and education. Cuts to the support they depend upon risk pushing them into poverty, debt and isolation.
The Chancellor has just announced a further £10 billion cut to the welfare budget. With £9 billion having already been removed from disability benefits and services in this Parliament, disabled people are already at a tipping point.

The report highlights the fact that disabled people are "twice as likely to live in poverty" and only a small loss of income can "tip people with a disability into greater dependence on health and social care services or friends and family".
The Department for Work and Pensions had "failed to consider" knock on effects of scrapping the DLA, the report claimed, citing examples such as increased burdens on council funded care if 500,000 people were to lose benefits.
It argued the £2 billion in savings expected by the Government from ending DLA is "overestimated" by potentially £1.6 billion.
Increased costs such as implementation; lost tax revenue; and increased dependence on council services, were predicted by the report to largely cancel out hoped for savings.
