Politically, this is magnificent. The Lib Dems have target seats throughout Surrey where they're typically the main challenger, they've been campaigning hard locally on water quality through most of this parliament (hasn't always got national attention but they worked out a while ago it's a very resonant issue in their target seats) and then just in time for the election Thames Water start warning people the water isn't drinkable...

The Tories really have screwed over everyone haven't they? Even the well to do in Surrey have shit in their drinking water.
