  Are they aquilegia leaves?
  If so, my many aquilegia plants have it and always do at this time of year.
  It's the older foliage that is dying back - they've flowered and done their job for the year so they're closing down until next year.
  Sometimes I cut the affected leaves off, usually I leave them until they've died off completely and tidy them up then.

   I agree. I am sure it is due to the dry conditions. Aquilegias flower in early summer and I don't think they like the increase in temperature as summer gos on. If it is bad cut the foliage off as said by @Pete.8 .

  Thank you both.   They’re not clear photos as I’ve cut most of the growth down.  It is a young plant in a pot and I’m hoping it is only powdery mildew but there are white patches, darker on the underside, which may be due to being too wet and in the wrong situation - not much air circulation. Fingers crossed.

  Not bad enough to worry.  You should see my Acanthus, almost snow-white.
