Blight

On my allotment blight has spread and got onto my potatoes and tomatoes. I read that the spores stay on the soil about 3 week before dying. After 3 weeks if I leave the soil alone, could I move some new tomato plants into the area? and maybe under plastic to stop more stray spores getting onto the leaves. They are in pots at the moment off the allotment and I would like to move them for more space. I wonder if anyone has experience of doing this? Thanks

Potato blight spores stay in the soil up to five years. I would not move tomatoes into that soil. Plant something from a different family like Kale.
Next year grow potatoes in a different space, and try a blight resistant variety like Sarpo Mira or Sarpo axona.

I have found Tomato Crimson Crush to be reliably blight resistant, if thats of help for next year.

Any tomato plants exposed to the elements will get blight at this time of year. Ditto potatoes if blight is about.
Last year I swapped tomato plants with a friend, as we have done in previous years ... sadly hers were infected with blight and all succumbed quite rapidly in the greenhouse ... as did all of the ones I gave her, with the exception of the Crimson Crush.
In my friend's greenhouse and in mine, the Crimson Crush remained healthy and cropped well although they have been in very close proximity to the blight-blasted ones ... just as described in this article published by the RHS
