presenter called out live on air about her previous CV claims.
The Chancellor has been given the moniker of Rachel from Accounts after being accused of enhancing her CV from her time at the Bank of England and Halifax.
At the end of her interview, Madeley said: "This is your first appearance on Good Morning Britain since quite a few months, and certainly since allegations about you enhancing your CV. We don't mean to embarrass you, but we just quickly like to go through it.
"You said you've worked at the Bank of England for a decade. In fact, it was only six years, and one of those years was at the London School of Economics doing a Master's course. So that's five years and not a decade."
He continued: "It was stated that you worked as an economist at the Bank of England, British embassy in Washington, and, latterly, the Halifax Bank of Scotland.
"But according to your former colleagues in your actual job, you actually worked in a support department at Scottish bank, and you sort of helped out with admin and it and that's all earned you the nickname of Rachel from accounts.
"Did you? Did you enhance your CV to make yourself look better qualified to be the Chancellor of the Exchequer if you won the election."
A stuttering Reeves responded: "I'm really proud of the jobs that I did before I became a member of parliament," as she went through her job history.
Madeley persisted: "Why did you say that you worked at the Bank of England for a decade, when, in fact it was, well, it wasn't even six years. It was five. I mean, that's exaggeration, isn't it?"
Reeves responded: "Well, I worked for the Bank of England for six years, between 2002 and 2006," as Madeley asked why she said it was a decade.
She repeated: "I think in the end, people want to judge me on the job that I'm doing today as Chancellor of the Exchequer. I'm qualified to do this job, but in the end, people are going to judge me.
"Am I growing the economy? Am I improving their living standards? I'm determined to do just that."
