Tie knot (7)

Ross

I believe the answer is:

windsor

(Other definitions for windsor that I've seen before include "somewhere in Berkshire" , "Royal palace" , "Knot type; royal castle" , "-chair; -knot; -castle" , "Family name replacing Saxe-Coburg-Gotha in 1917" .)

I've seen this clue in The Sunday Times and The Times.
