Here's the relevant bit from that BBC site http://news.bbc.co.uk/2/hi/uk_news/politics/vote_2005/england/4520257.stm

Marshall-Andrews surprised himself by holding his Medway seat after publicly declaring before the declaration he would lose it.

Mr Marshall-Andrews, who held his seat by 213 votes, blamed the "unpopularity" of Tony Blair for his reduced majority.

"My majority was 3,750, it's gone down to 213," he said.
