This week we are looking at how a Progressive Alliance can prevent a Conservative majority by coordinating together to win enough seats for a majority. Last time we looked at the arithmetic of such an undertaking, and defined which seats should be considered already safe. We found that of 284 seats that aren't safe, the Progressive Alliance would need to win 238 in order to outnumber the Conservatives and related parties.
We are now going to look at each region of the country to see where the key battles are. In this article, we are going to look at all the regions in the south of England.
