Last three, all interlinked (no letters for one) have me stumped. Explanations would be appreciated also. Hope my letters are OK. I believe they are, but .....
1D. Saw first sign of Alpine peaks (6) ?a???a
2D. Go to the Pasha, elevated to office, finally (4) ?e??
10A. Taking it easy in Frence holiday home? Au contraire! (4) ???? (linked to the other two)
For those still trying, methinks there's a slight error in 11A clue. Should be "bit" not "bits"
