### Clue: Like the centre of Bordeaux, without barriers and without weapons (11)
### Answer: DEFENCELESS 
 ### Explanation: DE is the centre of Bor-DE-aux + FENCELESS="without barriers"
 
 
I could also see a parsing where DE, FENCELESS is "Like the centre of Bordeaux", with 'fenceless' referring to a lack of outer letters – this would mean that "without barriers" becomes part of the definition
