Tomato blight?

[Ifailed]

I think this is blight, can you wise people confirm if it is?

If so, should I just pull up the whole plant and discard it (not in compost), it's outside and there are other tomato plants, and spuds, nearby?

It certainly looks like it. Best to dispose of it, and keep watch on your other plants as it will quite likely appear on those too.

I had this appear on the only tomato plant I had outside the greenhouse. I had to get rid of it.
