JUDGE David Griffiths, referring to Jing Wu, a Chinese national found guilty of running cannabis factories in Southampton, said he was not sure the public would think it reasonable for him to remain in this country.

I am surprised that there should be any question in the matter.

In view of the serious epidemic of mental health problems we are currently facing as a direct result of cannabis use by youngsters, I would recommend Wu be sentenced to life imprisonment to be served in a prison in his own nation.
