Just listening to your recent podcast with David and heard you mention your email address.Thought you and your dad might find this interesting.
Yesterday a friend sent me this photo of a letter from Dept. of Health & Social Care and Imperial College. This was one his sister-in-law had received for her child. My friend said he had also received one for his son (both in West Sussex).
Neither he nor his sister-in-law are keen on sending off their children’s DNA. I’m not sure why only children are being targeted.
