The elections for Councillors in London are being held tomorrow (May the 5th). So please get off your backsides and vote! If you want to get rid of the road closures in Lewisham, there is only one way now.
Polling stations are open from 7.00 am to 10.00 pm so there is really no excuse (unless you have already submitted a postal vote). There is typically a low turnout in local elections so those elected can be unrepresentative of the views of the electorate unless you cast your votes.
These are elections for your local councillors (and the Mayor in Lewisham) so vote for those who will best represent you - not necessarily on traditional party lines. This is not a referendum on your views of central Government but on how well your local borough has been managed.
But do make sure you vote tomorrow!
