LAST week, courtesy of BBC Radio 4's PM programme, I spent an afternoon at the Greenford Flyover in the company of an expert on urban environments.

He was appalled at the state of the subways and agreed with me that CCTV will not make it a safer place.

The solution to this problem is to place a structure housing some sort of 24/7 service or a combination of them in that space.

It does not necessarily have to involve the police. The best way to prevent another assault of the kind that led to the death of Ian Newtion is to enable that space to be used in a constant, positive way. CCTV to the value of £495,000 will not do that.

The flyover is a classic example of 'space left over after planning'. We are now paying the price for the mistakes made by planners who walked away from their efforts in the 1960s and 1970s without a backward glance.

Unfortunately Mr Newtion has paid for it with his life.
