I had missed the sticky centre of 11a, so thanks for that.
My fave definitely 13d, lovely elegant clue.
I actually enjoyed the 'primarily' clue this week, it was gloriously over the top! Poor Everyman, can't please all of the people all of the time... :-(
I was struggling to parse 4d and 15a - couldn't get the word play in either.
I got 15 from chrise's comment on page 3, thanks.
Also ta to chrise for 4d - I had had a wrong word for 'satirised' which explained why I couldn't parse it!
