It is hard to explain how stupid it is to say ‘his 84-year-old twin Sir Frederick’, and frankly if someone can’t see it, he or she is taking money under false pretences. The age of the twins needs to go in the second par, thus:
The 84-year-old twins Sir Frederick and Sir David Barclay are understood to be reviewing all of their key assets, which includes the Telegraph Media Group (TMG).
This immediately adds the fact that they are getting on a bit, and it does not assign an age to one twin leaving open the possibility that the other could be a different age.
As an aside, I have many times seen this kind of thing: ‘The twins, who are both 16’. Unless they were born each side of midnight at New Year, this goes without saying. You do not need to point out, either, that boy and girl twins are not identical. I know it is obvious but again it is something I have seen repeatedly.
Finally:
Sir Frederick and Sir David Barclay are understood to be reviewing all of their key assets,
‘all of’ is wrong. It should be ‘all their key assets’. Why add a word that is not necessary?
