Shabana Mahmood is currently the favourite to become Andy Burnham's chancellor.
That basically means she could end up in charge of the country's money, deciding things like taxes, government spending, and how much the UK borrows.
The Financial Times reports she is set to be named chancellor when Burnham takes office on 20 July, with people briefed on his plans describing the choice as settled. No appointment can be formal until he is actually prime minister.
Mahmood does have some experience.
She's held important roles in government before and is known for being disciplined and willing to stick to tough decisions.
People who support her might say that's exactly what's needed right now, someone who can keep control of Labour MPs and reassure businesses after yet another change in prime minister.
She could also be a good fit for Burnham personally, since they seem to think in similar ways, which might make running the government smoother.
But here's the issue: most people don't actually know what she would do with the economy.
She hasn't recently been in charge of major economic decisions. And she hasn't clearly explained her views on big topics like income tax, VAT, borrowing, pensions, or wealth taxes in one clear plan.
That matters a lot. Burnham is expected to become prime minister without a general election, meaning voters won't get a say first. So his chancellor, almost certainly Mahmood, could take charge of the country's finances without either of them having just won public approval for their economic ideas.
Mahmood also has another challenge. Some Labour MPs have already pushed back against her ideas on immigration. Being chancellor means convincing your own party to accept tough choices, like cutting spending or raising taxes, which can make people unhappy. Just being strict in one area doesn't mean you can control everything at the Treasury.
None of this means Mahmood would be bad at the job.
But it does mean people shouldn't just assume she'll be fine without asking questions.
Before she's put in charge of the UK's money, voters should know what she plans to do and who might end up paying for it.
Right now, they don't.
