Hello and welcome to Political Thinking, a conversation with rather than an interrogation

of someone who shapes our political thinking about what is shaped theirs.

Every so often there's an issue that bubbles up, if you'll forgive the metaphor, and reaches

beyond the Westminster bubble.

The issue we're talking about today is the issue of sewage, the quality of our waterways,

our rivers and our seas.

And my guess this week on Political Thinking is the man who's in short that no political

figure can ignore that question of the quality of our waterways.

He is keen angler, campaigner, an original lead singer with the undertones, Thurkall

Sharkey, a man who left the stage in order to campaign for musicians' rights before taking

up his current position as one of the country's leading environmental campaigners.

He began life in the bogside in Derry as well here.

He is now a hero to people from the Green Party to the readers of the Daily Telegraph,

the countryside alliance to surfers against sewage.

Thank you very much for having me.

Now you have been described as a strappy former punk rocker who won't take no for an answer.

Do you plead guilty?

If I am right in thinking that might have been a man called Michael Dugger.

And I think I'm seeing him a few days time, I'm going to have to demonstrate with him

over that former Labour MP.
