Down to last few but help would be much appreciated. 1d. Go on state trip (8) ??O???S?. Also 11a. Argentina's prince (3) ??S. (Thought on "Nas" as in Prince Naseem (boxer) which lies at end of Argentina's.) Thanks
Thanks (belatedly) Slioch. (Had to leave the computer for a while!) Have gone with "progress". However that means 11a now starts with "R" and I went with "Ras" rather than Aga. Thanks anyway.
