GRAYSON PERRY = Artist
G(ood) RA (Royal Academy = artist), with (clarit)Y, (finally), sad = sorry, about =
surrounding, broken = anagram of "pen" = npe Therefore SO - NPE - RRY
I couldn't make Grayson Perry fit as I had Marco Polo for 5 down (Travelling merchant hurt company with game 5,4) which would have placed an O at the end of Grayson.
Sorry, I know you may not have the crossword in front of you, but is there an alternative to 5 down??
