Panorama BBC1 tonight at 8.30...

Blackburn was once described as one of the most segregated towns in Britain by the author of a report on riots across northern England. In 2007, Panorama found Blackburn's Muslim Asian and white communities were living worlds apart. Ten years on, has anything changed?In 2007 we made a programme called White Fright tracking the ethnic and religious divide between Muslim Asian and white residents in Blackburn.

White residents were found to be leaving in large numbers and the two communities had separate lives.

A decade on Panorama has returned to find a town that is even more divided.

Some parts of Blackburn are only lived in by white residents and other areas are almost entirely Muslim Asian.

It's totally changed in my lifetime. There were probably about half a dozen Asian families here, nowadays there's probably half a dozen white families left, he says.

Mr Musa is worried about what his town has become and what the future holds for Blackburn.

After the 2001 riots that hit towns near Blackburn, including Burnley, Oldham and Bradford, Prof Ted Cantle was appointed by the home secretary to lead theCommunity Cohesion Reviewinto the causes.

He found a lack of understanding between communities in 2001 led to discontent and a couple of racist incidents that escalated into a disastrous situation.

It has been 17 years since his report but Prof Cantle says very little had changed for the better.
