Could someone please tell me what potato problem I have here?! The leaves are curling up and the plants look as if they are dying off. It's not affecting all the plants but I'm wondering if it will spread if I don't take the diseased ones out.

It could be blackleg, a bacterial disease.

Yes, pull the affected plants as soon as possible.

(Has it been warmer and damper than usual?)

Hi Pat

Many thanks for your reply and the RHS link - I will destroy the affected plants and hope for the best with the others!

Probably bacterial but check the pH of your soil. We had a similar problem several years ago that we solved by correcting the soil pH. I googled "pH for growing potatoes" and found this:

"Potatoes grow best in an acidic soil with a pH level between 5.2 and 6.0. It is possible for them to grow in a higher pH, but the risk of developing a disease called “scab” is more likely."

You may want to poke some hole in the ground around the potatoes, and
pour in some sulfur dust, in order to drop the pH.
