What did Labour do to the winter fuel allowance?
The winter fuel allowance - not something we expected to be speaking about quite so much when Labour won power last year, but an issue that's become synonymous with the party's unpopularity.
You'll likely recall it was one of the first policy announcements by the chancellor last July - she said it would help fill a 拢22bn "black hole" in Britain's public finances.
It had previously been a universal benefit for all pensioners to help them pay for their winter fuel bills, but Reeves made it means tested so only the very poorest still got it.
Who is eligible for the winter fuel payment?
Labour limited it to people over state pension age who are receiving pension credit or a limited number of other benefits.
These benefits are income support; income-based jobseeker's allowance; income-related employment and support allowance; universal credit.
The number of people eligible dropped from 11.4 million to 1.5 million.
Reeves has said that number will go up for the coming winter, but we don't know yet who'll be made eligible.
Details could come today, Sky News understands.
How much is the payment?
The payment is 拢200 for households receiving pension credit where the recipients are all under 80.
If someone in the household is over the age of 80, it's 拢300.
What were the rules before?
The payments were available to everyone above state pension age.
Most people got the winter fuel payment automatically.
We are not expecting Labour to revert to that. Mick Jagger, your winter fuel allowance has gone for good.
Ministers will want to save some face on their U-turn, and still make the case that only poorer pensioners need the payment.
Who is eligible for pension credit?
Pension credit is available to pensioners whose income falls below a certain threshold - the payment tops up their income to this amount.
For people with a partner, income is calculated together.
Income includes state and private pensions, earnings, and social security benefits including a carer's allowance.
But not everything counts as income - disability payments, housing benefit, and council tax reduction aren't counted.
Pension credit tops up your weekly income to 拢218.15 if you're single and 拢332.95 if you have a partner.
Pension credit is often described as a "gateway benefit" as it can lead to further support, including help with housing costs and council tax.
The benefit can be claimed by phone and online, and an online calculator can help pensioners check if they are likely to be eligible and get an estimate of what they may receive.
