Potatoes near greenhouse, increased chance of tomato blight?

Hi everyone, sadly last year my first attempt at growing tomatoes in the greenhouse was ruined by blight. I know it's quite unlucky to get it indoors so I blamed the potatoes in the veg garden next to the greenhouse, personally I'm not a huge fan of potatoes so I planned to leave them out of the garden this year, but I've just got back from a busy period at uni & work today & it seems my dad decided that he would be helpful & get some potatoes in My question is, does the close proximity of the potatoes increase the risk of blight in indoor tomatoes?
