A former banker, who began supplying crystal meth after being diagnosed with terminal cancer, has been condemned to die in prison after being sentenced to 11-years.

In a plot mirroring that of the hit US television drama, Breaking Bad, David Parkinson, 34, went into the deadly drug business after being told his illness could not be cured.

Recruiting his mother Diane as his bookkeeper, Parkinson travelled from his home in Lancashire to London to buy large quantities of the highly addictive drug.
