African girl welcoming Vikings (8)
I believe the answer is:
sudanese
'african' is the definition.
(Sudanese is an example)
'girl welcoming vikings' is the wordplay.
'girl' becomes 'Sue' (girl's name).
'welcoming' means one lot of letters goes inside another (in sense of 'inviting in').
'vikings' becomes 'danes' (I've seen this before).
'sue' going around 'danes' is 'SUDANESE'.
(Other definitions for sudanese that I've seen before include "Bad danseuse from a northeastern African state" , "Sue Dean's a native of the African state" , "Africans" , "African inhabitants" , "Of Khartoum, say" .)
