manama

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

'capital city' is the definition.
'Manama' can be an answer for 'city' (Manama is an example). I'm not certain of the 'capital' bit.

'old lady touring one' is the wordplay.
'old lady' becomes 'mama' (I've seen this in other clues).
'touring' means one lot of letters goes inside another (touring can mean going round).
'one' becomes 'an' (an apple is one apple).
'mama' enclosing 'an' is 'MANAMA'.

Can you help me to learn more?

(Another definition for manama that I've seen is " Capital of Bahrain".)

I've seen this clue in The Sunday Times and The Times.
