Canterbury City Council Bill

I am sorry to ask a question that might have been dealt with in detail in the previous Parliament, but for my benefit will my hon. Friend explain whether the Bills offend against any ancient charters of the towns and cities that we are discussing? In Nottingham, there are freedoms given to citizens of the city, on which the hon. Member for Nottingham East (Chris Leslie) will no doubt be able to enlighten us, and in Canterbury there are freedoms under the original monastic charter, which no doubt my hon. Friend the Member for Canterbury (Mr Brazier) will tell us about. I wonder whether the Bills might offend and go against those ancient liberties, which have been granted for so many hundreds of years, and whether the issue has been discussed.
