Article by magazine about graduate touring one country (3,6)
I believe the answer is:
the gambia
'touring one country' is the definition.
'the gambia' can be an answer for 'country' (The Gambia is an example). I'm not sure about the 'touring one' bit.
'article by magazine about graduate' is the wordplay.
'article' becomes 'the' (the definite article in English).
'by magazine' becomes 'gaia' (I can't justify this - if you can you should give a lot more credence to this answer).
'about' means one lot of letters goes inside another.
'graduate' becomes 'MB' (someone with a Bachelor of Medicine degree).
'gaia' going around 'mb' is 'gambia'.
'the'+'gambia'='THE GAMBIA'
(Another definition for the gambia that I've seen is " Country".)
