== New Towns == 

 Hi there. With respect, I don't think your line added to New towns in the United Kingdom 
 "Some were completely new, while others were expansions of existing settlements, sometimes known as "expanded towns"" is really very helpful. The New Towns proper were a specific set of towns, known as New Towns, to which the article relates. They were originally intended to be largely self contained ('sustainable'), and developed by the Commission for the New Towns through development corporations. Expanded Towns were a later and much watered down concept. The London overspill article contains a fuller list of new and expanded towns.
