Sir - I couldn't agree more with your recent editorial, highlighting the city council's financial woes and calling for all political parties to put the good of the city above political posturing.

The Green Party has proposed a 'traffic light coalition' twice in the last two years - an executive arrangement between Labour, Lib Dem and Greens - as the only way to break through the party political bickering and bring solid leadership to the council.

Unfortunately, both Labour and the Liberal Democrats have rejected this option on both occasions.

I hope that your editorial may help them to think again. The Green Group's door is always open to constructive politics, and our city badly needs a co-operative approach.

Matt Sellwood, Deputy leader, Oxford City Council Green Group
