Sixteen- and 17-year-olds pay taxes and can join the army, so surely they should in turn be given their right to vote.

At times unpopular measures are needed in order to change behaviour.

In the current climate motorists have a long list of issues from which to choose to raise on the doorstep. Policies aimed at reducing emissions - like the changes to Vehicle Excise Duty or here in Manchester the proposals for congestion charges - are not without controversy.

It's become unfashionable to celebrate political achievement, and Labour achievement even less so. And it's positively uncouth to be proud of something that this Labour government is doing. So, slam me for saying so, but I'm really proud of the NHS.

Surely, the best and most effective measure is to get the economy moving and shorten the period of recession or slowdown. That's the rationale for Gordon Brown's "fiscal stimulus" and it sounds like a good one to me.

Some argue that now isn't the time to push the green agenda - that all efforts should be on preventing a serious recession. That is a false choice. It fails to recognise that climate change and our carbon reliance is part of problem - high fuel prices and food shortages due to poor crop yields compound today's financial difficulties.

As the economy faces such difficulties, more tough questions need to be asked about what the Tories would do if elected. Their ideology of free markets and small government needs challenging. That has to be part of our job.
