Whilst it's only a very small sample, interesting to note that of the four Estonian satellite-tracked LSE the furthest North has only just crossed into Egypt. The seventh primary looks very long to me too.
Edit:- Just looked at the 8 tracked GSE and they're all much closer to home - 3 just South of Istanbul, the rest in Europe with 3 very far North.

IMO it looks similar to this GSE https://www.birdforum.net/showthread.php?t=327836
All german LSE still in Africa, no barring visible to make a definitive ID, still visible iris would be at odds with GSE

Agree. The primary patch on the upperwing is also confined to the shafts and lacks the blob commonly seen on Lesser Spotted.
ok, any comment on bill and iris?

Not the best angle for judging iris colour - from what I can see it does look pale - but it would be very useful to have more of a head-on shot to be certain. I'm not sure if the angle may be having an effect on the appearance?
I find it difficult to separate the two species on bill size as it seems there is some variation. A big billed GSE should look quite different to a small billed LSE but I think some GSE with smaller than average bills are likely to cause confusion.
By the way Tom I would be interested to learn more about the German LSE you mention - is this a satellite tracking project?

Yes they are satellite tracked but unfortunately the website is no longer updated. Bernd Meyburg made a post yesterday that one male is still in Uganda and the other LSE not even in Egypt, which means they are really late

Thanks Tom - a shame it's not possible to follow their progress online.
Looking back I found a post from Fernando Alonso (fdokykcu) regarding iris colour where he quoted DF.
"The*iris*colour remains a reliable feature when seen well. In LSE the*iris*has a pale yellowish colour in all but juveniles and first-year birds, while in GSE it remains dark throughout life, although some adults show a lighter, medium brown*iris, but never the bright amber or almost pure yellow of adult LSE"*
Hard to say from the OP's photo just how near the iris colour is to the description.
