What attracts people to Leeds on tours (9)
I believe the answer is:
lodestone
'what attracts people' is the definition.
(a lodestone attracts attention)
'to leeds on tours' is the wordplay.
'tours' indicates anagramming the letters (the letters roam or tour around).
'to'+'leeds'+'on'='toleedson'
'toleedson' with letters rearranged gives 'LODESTONE'.
(Other definitions for lodestone that I've seen before include "Mineral" , "Magnetite" , "focus of attention" , "Magnet" , "naturally attractive?" .)
