Sunday Times Cryptic

[mra1]

Have completed but not sure of the wordplay for 3 of them viz 15AC Passing appeal to head of state (5) I have O?ing which I can only find owing to fit in (the O is definitely the last letter of the Norwegian City); 23AC (4,2) Jolly soiree abroad with victory for Italy E?E?, S? I can only get Ever So here and (22)D (3,3) Email correspondent important to get one in place ?E? P?L for which I have net pal - can anyone confirm I was on the right lines and if so why

[dr b]

OKing (approving or passing)
ever so is correct
key pal (imporatnt = key)

[dr b]

everso = anag of SOIREE with Victory subbing for Italy

[Lie-in King]

15a O-king
23a Ever so - anag 'so(I)ree', replacing 'I(taly)' with 'v(ictory)'
22d Key pal - 'key' (important) + 'a' (one, in) 'pl(ace)'

[jim360]

15a OK'ing (O = appeal, king - head of state) ?

Not sure on the others.
