Liz Truss could put off a decision on benefits for weeks – leaving millions of families dangling as they wait to find out if they will be hundreds of pounds worse off.
Ministers admitted the Prime Minister could wait until the end of next month to make a call on whether to increase payouts in line with rising prices next April.
A working couple with two kids would lose £752 over the year if benefits including Universal Credit rise in line with average wage increases instead, according to the Resolution Foundation.
