There is a few aspects to your question that I will address separately below. Note however that we do not plan itineraries so that choice will be up to you.
- When entering Iran I'd still have with me a UK passport β no Israeli stamps on this option. Would that be fine? My doubt here is that as British citizen I'd need to visit Iran with a tour or with sponsor. Although I'll not be using UK passport, they could find out and apply this rule to me?
This should be fine actually. We had a similar question for a Dutch/U.S. dual national here who contacted both his Dutch embassy in Iran and the Iranian embassy in Hague and both confirmed it was fine to enter with the Spanish passport even though he also has U.S. citizenship. If you are very anxious you could still confirm with your respective embassies but I would expect no trouble.
- When entering Iran using Spanish passport, I'll still have with me a UK passport β possibly with a Israeli stamp. Is it wise to just hide it somewhere? What are the chances of them to find out? What would be de consecuences?
Honestly I would not risk this one, but that is my opinion as a fairly risk-averse person. The point is, if you are breaking their rules, why carry evidence of that with you?
Instead could you leave your British passport with Israeli/Jordan stamps with a trusted person or even mail it home?
- I'll come into Israel with a recently issued UK passport and I expect to be questioned. Should I assume that I'd be requested to show the Spanish passport and give explanation of my Trip to Iran?
YMMV. Emigration/immigration in Israel can be incredibly harsh and a trip to Iran sure does not help, in itself it is not a no-go either. Have a true and plausible story for everything and be able to prove it in case.
