Charge politician and sweetheart to enter Toulouse's ground (8)
I believe the answer is:
stampede
'charge' is the definition.
(I've seen this before)
'politician and sweetheart to enter toulouse's ground' is the wordplay.
'politician' becomes 'mp'.
'and' says to put letters next to each other.
'sweetheart' becomes 'e' (the heart/centre of 'sweet').
'to enter' indicates putting letters inside.
'toulouse's ground' becomes 'stade' (I can't justify this - if you can you should believe this answer much more).
'mp'+'e'='mpe'
'mpe' inserted inside 'stade' is 'STAMPEDE'.
Can you help me to learn more?
(Other definitions for stampede that I've seen before include "Panicked rush (of cattle)" , "Beastly charge" , "Uncontrolled rush" , "Crazy pets made a sudden rush" , "Rampage" .)
