Will have a ponder at this on the weekend.

I will need a pen and paper sort of lost track - did work one out but the others need notes

I've done the one with flags, which wasn't too hard, but a bit baffled by the others so far....

Managed 1,3, 5 and 7 (I think)

I found #3 very quickly. I've also found an answer to #1, again very quickly, in fact so quickly I can't believe it's correct. Solved #7.

Ross Kemp solved it in seconds while on the loo.

Finally cracked it. Number two was a bit devious IMHO and number 5 I had to reverse engineer
I just looked for a 7 letter anagram in the 10 letters and then checked the maths !
I'm sure that there is an additional puzzle in the picture but I haven't figured it out yet.
