June 16.

Your television critic Julie Davidson has attacked the integrity of

our highly successful and popular documentary series Cutting Edge (June

5).

She claims that this series in the hope of stirring up controversy

''has produced some very dodgy documentaries indeed''.

This is a completely unjustified attack on Channel 4's journalism and

I will not let it go unchecked. It was Cutting Edge that exposed abuses

at Ashworth Special Hospital which were vindicated by the subsequent

Blom-Cooper inquiry.

Revelations about the inhumane treatment in another film in a Greek

mental hospital led to an EC inquiry.

Last month a Cutting Edge film about loan sharks in Strathclyde was

praised by the Royal Television Society for the courage of its

journalism.

Of course, we welcome hard and fair criticism of our programmes but

this unwarranted and one-sided attack on a first-class series is

unacceptable. I suggest that your readers look in on Saturday nights to

The Best of Cutting Edge and make up their own minds about this award-

winning series.
