Everyone included in check on outskirts of Tirana, the capital (8)
I believe the answer is:
valletta
'the capital' is the definition.
(Valletta is an example)
'everyone included in check on outskirts of tirana' is the wordplay.
'everyone' becomes 'all' (I've seen this before).
'included in' indicates putting letters inside.
'check' becomes 'vet' (I've seen this before**).
'on' means one lot of letters go next to another.
'outskirts of' says to hollow out the word (remove centre letters).
'tirana' with its centre removed is 'ta'.
'all' put into 'vet' is 'vallet'.
'vallet'+'ta'='VALLETTA'
(Other definitions for valletta that I've seen before include "Maltese capital" , "Capital of Malta" , "Hard biscuit" , "my neighbouring capital" , "Malta's capital" .)
