Tories welcomed by peer turned up in seaside resort (8)
I believe the answer is:
brighton
'seaside resort' is the definition.
'tories welcomed by peer turned up' is the wordplay.
'tories' becomes 'right'.
'welcomed by' means one lot of letters goes inside another (letters welcomed inside).
'peer' becomes 'nob' (nob can mean an aristocrat).
'turned up' says the letters should be written in reverse.
'nob' back-to-front is 'bon'.
'right' inserted within 'bon' is 'BRIGHTON'.
'in' is the link.
(Other definitions for brighton that I've seen before include "Resort on the south coast of England" , "Where the Prince Regent built his Pavilion" , "resort town" , "seaside location" , "South coast city combined with Hove" .)
