Hi, I agree microstates should be added to E gates. Must be very frustrating if citizen of San Marino, Andorra or Monaco to have to wait ages in long queue. Considering wealth of those countries and next to zero chance of overstaying etc. Should also expand list of eligible nationalities (UAE, Qatar, Saudi, Bahrain, Kuwait, Brunei etc perhaps).
I would also like to see the EU countries reciprocate and allow British citizens to use E gates like UK allows them to use.
I know some countries now do this, like France, Spain, Portugal, Italy and Cyprus now allow E gate use for UK passport. However many still not such as Netherlands and Germany.
