asked the Minister of Supply what improvements in security measures have been effected in the last two years at Royal ordnance factories to prevent the employment of undesirable persons.

The policy, as announced by the Prime Minister in March, 1948, of excluding unreliable persons from access to defence secrets is applied to the Royal ordnance factories.

Can the right hon. Gentleman assure us that the measures he has indicated are sufficient to prevent the employment as editor of the "R.O.F. News" of a man with two convictions for assaulting the police and who has been a well known Communist since the war?

I am not prepared to answer about individual cases.

Why not.

Is there any security in ordnance factories?
