Liberal Democrat MP for Glastonbury and Somerton, Sarah Dyke, has criticised the Government's proposed welfare reforms in Parliament this week, warning that they threaten vulnerable people across her constituency, including residents in Street and Glastonbury.

Ms Dyke voted against the welfare reform bill and described the legislation as "botched", highlighting the case of a local constituent who she said would be plunged into poverty under the planned changes.

"Jackie from Street suffers with Crohn's disease, fibromyalgia and mental health issues," Ms Dyke told the House of Commons. "She worked for most of her life until ill health made it impossible. Under the reforms, she will lose her entitlement to Personal Independence Payment and Employment Support Allowance, plunging her into poverty."

The Government's original proposals included changes that would have cut support for new Personal Independence Payment (PIP) claimants, created a two-tier system, and risked pushing disabled people out of work. The changes also threatened the Carer's Allowance for thousands of carers if the people they supported became ineligible for PIP.

While ministers announced some last-minute concessions following backbench pressure, Ms Dyke said the bill still contained "harmful" measures and had been rushed through Parliament without a full impact assessment.

"This welfare bill has been botched from start to finish," she said. "The scale of the rebellion from the Government's own party yesterday makes it clear how damaging and dangerous these reforms will be, and how harmful to the most vulnerable."

She added that although the Government had rolled back the most damaging proposals—meaning people like Jackie, who are already diagnosed, would still receive support—it remained "totally unfair and wrong" that anyone newly diagnosed in future could be excluded.

"The most vulnerable people in society and their carers, who rely on PIP to survive, must not be harmed any further by devastating cuts," she said. "We must urgently rebuild our health and social care systems to support people properly who are struggling with chronic illness, disability and pain, or caring for others who do."

Ms Dyke called on the Government to work cross-party on a "fair and practical approach" to managing welfare costs, and said she and her Liberal Democrat colleagues would continue to oppose the bill.
