Just circling outskirts of Prague for all to see (6)
I believe the answer is:
openly
'for all to see' is the definition.
(out in the open)
'just circling outskirts of prague' is the wordplay.
'just' becomes 'only' (synonyms).
'circling' indicates putting letters inside (circling can mean going around or containing).
'outskirts of' suggests removing the centre (only letters on the outskirts).
'prague' with its middle removed is 'pe'.
'only' enclosing 'pe' is 'OPENLY'.
(Other definitions for openly that I've seen before include "(Done) without concealment" , "In an overt way" , "Without concealment, frankly" , "Overtly" , "Above board" .)
