Please stop my wipers squeaking!

Help!
We have a 2015 Cooper S.
It is perfect in every way except the wipers squeak.
I had changed the blades and it seemed OK for a few days then the noise returned.
We've driven two hours in the rain today and nearly went bonkers.
Could it be something on the windscreen or the mechanism?

Thanks for the advice. I suspect the angle of attack. I will talk to the dealer as it is new car.

Now booked in for MINI to fix.
The car is one of the first 5 door hatchbacks so I'm interested to know if this is a little gremlin.
