Don't hold me to the truth of this, but my neighbour just knocked on my door to tell me that he's just seen a punch-up in Sainsbury's car park caused by the traffic congestion.
Perhaps Glyn might be able to tell us the real story.
Sorry to have alarmed you Catherine. I was not really being serious. However, there is without doubt a traffic problem in Harringay and a universal solution will help us all.
