The Press Association presented a useful Q & A on universal credit and who will be affected, while a new row broke out among senior Tories on welfare reforms.
– What is the universal credit?  UC replaces six existing benefits: income support, income-based unemployment allowance, pay and employment allowance, housing allowance, work tax credit and children's tax credit – with a single payment.
– When is it introduced?
UC was launched gradually across the country, starting in pilot areas in 2013. So far, only new applicants for subsidies have been introduced into the system.
But since July 2019, about 2 million people are already receiving the old one the benefits will be transferred to UC, in a "managed migration" that will not be completed until 2023.
Among those who will be transferred to UC there will be about 1 million working families and 745,000 people unable to work because of long-term illness or disability
– Someone will lose?
The government has provided some "transitional protection" money, which the ministers say will ensure that none of the current applicants are subject to a cut in payments in monetary terms unless their circumstances have changed.
– Will there be a wait for payments?
UC is paid in arrears, and the first payment is not made up to five weeks after filing a claim. Applicants can request advance payments to avoid difficulties while they wait.
– Why is UC introduced?
Ministers say the new system is simpler and easier to understand than the old benefits. They believe it creates incentives for applicants to do temporary work or increase hours.
Secretary for Work and Pensions Esther McVey says that when the UC will be fully implemented, it will provide £ 8 billion of benefits annually to the UK economy.
