called out after she turned down appearing on 's The Money Show.
The presenter, 52, was hoping the Chancellor would join him on his show after announcing Labour's first Budget in 14 years.
However, the money saving expert confirmed on X that the politician would be a no-show, despite making the request weeks ago.
He wrote: "So it looks like@RachelReeves isn't coming on @itvMLshow live budget special tonight 8pm. We put in a bid weeks ago (for live or pre-recorded). Was told it was being considered, but have not heard anything.
"Shame as we're most watched current affairs show on TV by miles, no idea why her press team would put her on far less viewed political shows but not mainstream consumer tv?"
Martin added: "Don't worry though, it means more time for me to go through the detail of what it means for you (and the chancellor misses the chance to give her interpretation)."
Martin's followers flocked to the comments as they speculated the reasons behind Reeves' absence, with one writing: "She's scared, they know they've lied."
Another agreed: "Because she's a coward! You will run rings round her and question her decisions...... and she doesn't/ can't answer them..."
A third fumed: "She has no spine. Absolute cowardice from her, especially when it could have been pre-recorded and no doubt edited."
On Wednesday (October 30), Labour unveiled a debut budget plan that includes £40 billion ($51.8 billion) worth of tax rises to plug a hole in the public finances.
Ms Reeves also detailed increases to capital gains tax and private school fees, a freeze on fuel duty and the abolition of the controversial "non-dom" tax regime.
Choices made by Ms Reeves will see the overall tax burden reach a record 38.3% of gross domestic product (GDP) in 2027-28, the highest since 1948.
Despite Labour's promises to protect "working people", a £25.7billion increase in National Insurance (NI) contributions paid by employers is likely to reduce wages and lead to job losses.
