What next for Universal Credit, post Iain Duncan Smith?

Iain Duncan Smith resigned on the evening of Friday 18 March, a political earthquake whose aftershocks will continue to affect the government in the months to come.
Iain argued that the Treasury has consistently asked for savings from a single source – working age welfare – without considering first how best to reform the system, in order to deliver sustainable savings, and better outcomes for people.
Policy in Practice has said that the government would not be able to take money out of working age welfare without hitting the pockets of vulnerable people, or the employment prospects of people out of work and the lowest paid.
We look forward to working with Stephen Crabb MP to deliver a welfare system that is simple, rewarding and effective.
