Was delighted at the response I got when collecting signatures for the 20's Plenty campaign outside Elm Grove school on Friday.

I've blogged about 20's Plenty before, but I'll re-state the figures, because they're pretty compelling: 1 in 40 pedestrians struck by a car at 20mph die, compared with 1 in 5 at 30mph. At 40mph the fatality rate rises to around 90% with only one in ten pedestrians surviving a collision.

Parents were happy to discuss their concerns on safety, and seemed delighted that someone was taking an interest in making roads safer for children to cross. And a lot of them said they would be voting Green come the election, which is something I've heard more and more.

While out canvassing on Saturday this was very much the mood on the doorstep - that residents feel betrayed by Labour, and disenchanted by the Conservatives.

People are excited here by the fact they have a genuine other option to vote for, who will represent them with an independent and honest voice in Parliament.

By the way, recently, as you may have seen, there have been some negative campaigns on internet sites about myself and other local
parliamentary candidates.

I found this really disappointing because until now the local campaign here had been really clean and positive.

Political campaigning in the age of the internet is immensely challenging and complicated.

Cyberspace is a medium that is easily open to abuse. Never before have individuals been given so much freedom to express their views to so many; but with this freedom comes also the need for self-control and responsibility.

So I pledge to continue to use electronic media - whether they be websites, blogs, twitter or Facebook Groups - with honesty and
integrity, and I call upon all of my supporters and all Green Party members to do the same.

Our proposed Clean Campaign Pledge was designed as a way of trying to ensure that we have a clean campaign here in Brighton - and I'm still hoping other candidates will sign up too!
