I think that Miss Addlington (who only went to the games to gain experience) Has done a fantastic job for team GB.
I really don't think that making her a "Dame" at 19 is a good idea, Kelly Holmes was a lot older, and worldly wise. Young Rebbecca whilst grounded, stable and a delightful young woman, is going to have the shock of her life when she returns to Great Britain, and finds that the new shoes she likes, are presented by the owner of the company.
She needs time to take it all in, and decide what SHE wants to do, not what other's with commercial interests in mind may try to entice her with.
If there must be a title (and I suppose there will be) then may I suggest Chris Hoy?
Miss Addlington will have a pool and leisure center named in her honour, and from her television interview, she just wants to go back home and live with her family again.
Let's let her do that.
