Could you put up a photo of the thing that trip? I think everyone assumes it's an RCD but just to be sure.

If it's tripping out the whole board it must be double pole

That good eh?
I'll get a picture tomorrow. I dontnknow why but I always get this wrong and it throws all the advice people can give.If it's tripping out the whole board it must be double pole
Yes. And I see now, it is double pole?
I have a new switch so can fit that and examine the visible wiring for any defects. Beyond that I think I might need to get someone who knows more than me to take a look. I just dont want to buy a new cooker and then find out its a wiring or switch fault!

Disconnect the wiring where it goes into the back of the cooker, stick it in some choc strip or wagos, and try it.
If it doesn't trip you know its down to the oven and you aren't chasing a red herring.
If it is the oven then it is leaking to earth and to trace that further you are really going to need an IR tester.
Another thing you could try is disconnecting the element and try it - just to double check.

Would not just connecting a length of cable from the cooker MCB, having pulled the existing circuit cable from the MCB first?
Ok definitely not ideal and not to be recommended, even if temp cable is undersized, say 2.5 T&E, for a quick test, if cooker, when turned on does not trip DP switch it eliminates a fault with the cooker.
Then it's a case of fault finding, wall switch, cable.

I'd suggest not disturbing any of the fixed wiring, especially as it is unlikely to be the issue.
All that is needed really is to verify that the issue is only present when the oven is connected, and that the OP hasn't been unlucky enough to have a separate wiring fault that just happened to manifest itself at this particular time.
If there is some sort of intermittent issue, avoiding too much disruption makes it easier to try and pinpoint it.
Alter too much at one time and you’ll end up chasing your tail for weeks. So try and do it in methodical steps.
