Martin Lewis is seeking clarification over a missing detail in Rishi Sunak's 2021 Budget.
The Chancellor delivered his economic outlet in a 51-minute House of Commons address earlier this afternoon.
Vowing to help businesses, he said coronavirus has caused one of the "largest, most comprehensive and sustained economic shocks this country has ever faced".
And during the speech, he confirmed an extension of the UK-wide Self Employment Income Support scheme to September 2021, with 600,000 more people who filed a tax return in 2019-20 now able to claim for the first time.
But according to the M.E.N, Martin Lewis has now picked out a detail about the announcement which wasn't mentioned.
In a tweet, he said: "According to the docs SEISS 4 will be claimable from late April.

"That will be a blow for many of the self-employed who are desperate for the money now - and relatively is much later in the schedule than previous grants. I am awaiting confirmation and hope I'm wrong #budget21."
The news has left some people 'sick with worry' and concerned about how they will survive going forward.
One said: "It’s genuinely made me and no doubt others feel sick with worry. CJRS are ok every month. We are not. It’s cruel."

Another wrote: "I have no idea how I will survive until then. I've just had to make the last payment stretch from September to now, I was hoping it would be this month, not in 2 months time."
And a third wrote: "Why are they doing this to us... it seems so unfair that anyone on furlough gets their income monthly but self employed who aren’t able to work and are genuinely struggling are having to wait so so long."
