I'm a little stuck... Click here to teach me more about this clue!

'having been defeated' is the definition.
I can't tell whether this defines the answer.

'i'd allow changes' is the wordplay.
'changes' indicates an anagram.
'id'+'allow'='idallow'
'idallow' is an anagram of 'LAIDLOW'.

Can you help me to learn more?

I've seen this clue in The Daily Mail.
