Despite feeling that I did no wrong I will in future take extra care to ensure I promote cyclists as courteous and polite users of the highway.
Depending on the width of the road and without local knowledge, assuming both lanes are of equal widths, a few scenarios spring to mind ;-
1) If the parked vehicles on your side of the road left enough room for you to safely pass without crossing in to the opposing carriageway, then no probs, all over to the 4x4 driver.
2) If the length of the parked vehicles and layout of the road, left you committed to the opposing carriageway, before the 4x4 driver came in to your view, then no probs, over to the 4x4 driver to give way to you.
3) If the layout of the road also gave the 4x4 driver no view of you as you started to pass the parked vehicles, then shared responsibility.
4) If you were both in full view of each other as you approached the parked vehicles and the width of the road around them left you with no choice other than to cross the centre line markings in to the opposing carriageway, then my initial thought is that unless the vehicles in your lane are all very wide, there is probably not enough room for you to both share the opposing carriageway and the responsibility comes back to you to give way.
