Some will say that Badenoch was simply telling porkies, but I think more likely, frankly, that she simply wasn't across the detail of the trade deal enough to know:

Kemi Badenoch agreed to trade deal tax arrangement, say Indian officials
Conservative leader talking ‘rubbish’ after denouncing national insurance carve out
May 7, 2025 14:38She's basically clueless and opposes everything Starmer does for opposition sake. I'm not sure she even listens properly to anything.
Yeah, it is real 'I'm rubber you're glue' stuff from her a lot of the time.
Every single time she does this - it's infuriating. She needs some kind of AI agent to remind her of what she has already said or done
There's a version in which she knows about the demand but doesn't sign it off unless India makes a far better offer to the UK. That would be reasonable. But she doesn't make the case so I suspect she wasn't sweating the detail as you suggest.
If "Kemi didn't actually have a clue what was going on" is an option it is almost certainly the correct one
I'm shocked, shocked that Kemi Badenoch talks balls
How much longer can this go on for, surely the Conservatives are going to tire of her obvious incompetence soon
Could collapse at any time but equally could stagger on for years.
Whenever the question is “was BadEnoch to lazy and stupid to understand part of her job?”
The answer is always yes
Hopefully these Indian workers get a taste for whisky while they are here
Someone on her team should have checked out first.
Suspect this a trap by Labour into which Kemi fell
Looking forward to her going on the news to explain she's not a liar, she's just dumb and half-arsed.
A much more damning verdict on her abilities in my opinion.
