Yes I think the £20 uplift to #UniversalCredit should be permanent (important for adequacy of social security system), but here's a thread just focusing on the year ahead. Extending the lifeline for (at least) the next year is the only sensible option given the economic context:

(1) A look at the economic context tells us this income support is still as important as ever. Unemployment (already high at 5%) is expected to rise much further this year. OBR forecasts it to peak Apr-June and, due to a v slow recovery, stay above 7% until spring 2022

(2) Ending the uplift this April times the cut to coincide with peak of unemployment rate, ending support when needed most. What about a 3/6 month extension? This doesn't solve the issue. Given unemployment falls slowly, by July/Sept it'll still be higher than it's current rate

(3) So if the Government wants to ensure it supports people through the crisis, the only sensible option is to extend for (at least) the full year to April 2022. Anything less fails to respond to the economy reality, instead hampering our recovery and trapping families in poverty

(4) Yes the economic picture is full of uncertainty. Unemployment may rise faster, or the peak might be lower if furlough is unwound carefully and the health crisis improves sooner. But any shorter extension than a year is gambling on a very uncertain best-case outcome.
