Is it just me, or is thee something odd about this week's? I found myself solving it from the bottom up which wasn't always very helpful.
Anyway I'm stuck, to my annoyance, on 2 :
4D - A painful separation, sacking church singer (4)
W?E?
&
28A - Spy creature found by baker, heading off (4)
N?R?
It is always possible some of the letters supplied aren't strictly accurate.....
