OK, I thought, perhaps naively, that after the big fuss about Asda etc selling these last year they had all been withdrawn. However I was in Tesco this morning and they had a huge display of padded bras marked "teen range" sized from 28AA. These were brightly coloured plunge type bras and although marked as teen range were next to the 8-9 year old clothes. I've sent an e-mail to tesco but am cross with myself now that I didn't ask to see the manager and say something there and then.
Will be interesting to see what response I get from them.
