YOUR ‘Fly in the Ointment’ column produced another eyepopping expose for Guardian readers (Warrington Guardian, October 28).

Speaking of the public doing your job for you (unpaid), I have been struck by how many supermarket checkouts are now self-service as opposed to actually serving the public by installing more checkouts.

But to return to your mystery columnist, he has saved the best for last.

Apparently Warrington South MP Andy Carter voted to allow water companies to continue to pump sewage into our rivers.

In view of cases of E Coli poisoning through water supplies, is this constituting a ‘dereliction of duty’ as well as a betrayal of Warrington itself ?

Looks like the green agenda is also a brown agenda.
