Lots of politicians do OK on links and connexions (7)
I believe the answer is:
parties
'lots of politicians do' is the definition.
'parties' can be an answer for 'lots' (party is a kind of lot). I am unsure of the 'of politicians do' bit.
'ok on links and connexions' is the wordplay.
'ok on links' becomes 'par' (I can't justify this - if you can you should believe this answer much more).
'and' is a charade indicator (letters next to each other).
'connexions' becomes 'ties' (tie is a kind of connexion).
'par'+'ties'='PARTIES'
Can you help me to learn more?
(Other definitions for parties that I've seen before include "Celebrates" , "celebratory occasions" , "Social gatherings" , "Fun affairs for political groups" , "They may be thrown" .)
