Just in case the full import of today's story gets overlooked... a single piece of devastating evidence in the News of the World phone-hacking scandal has emerged.

The central point of the story is in the headline, Phone hacker 'passed information to several News of the World journalists'.

That's 'journalists' plural. A document put before the high court included a statement by the convicted phone-hacker Glenn Mulcaire in which he admitted dealing with several executives:

"Information was supplied to the news desk of the News of the World. This was manned by different people, [Mulcaire] cannot now recall who in respect of this claim he passed the information to."

Of course, it's possible that not all the information he supplied was the result of intercepted voicemail messages. But it beggars belief that none of it came from his illegal activities.

After all, what was he being paid £100,000 a year to do that regular reporters could not?

The new evidence, argued a lawyer for one of the people suing the paper's Wapping parent, News Group Newspapers, "hits NGN's [single rogue reporter] defence for six."

So I ask once again: when will Wapping tell the truth, the whole truth, and nothing but the truth? Evidence is being extracted bit by painful bit from the publisher as its defence unravels.

For years it has maintained that no-one else in its employ was involved in hacking beyond Mulcaire and its former royal editor, Clive Goodman.

Then came the suspension of a News of the World reporter, Dan Evans. Then came the suspension of its assistant editor (news) Ian Edmondson. Then came the discovery of previously "lost" emails.

Now comes Mulcaire's admission, which isn't his first major revelation despite the suspected funding of his legal costs by News Group.

Several NoW staff have told the New York Times and Channel 4's Dispatches that they knew about hacking and that their former editor, Andy Coulson, knew about it too.

Yet the publisher - alongside, incidentally, the Met police - continue to frustrate the court by refusing to be transparent by handing over unexpurgated documentary evidence.

Imagine the reaction from Wapping's red-tops if a government department did the same? They would howl long and loud.

Instead, NGN obfuscates and obstructs with impunity. Only The Guardian and The Independent are covering the unfolding daily drama in the courts.

Where is the Daily Mail when you want it? Or Wapping's paper of record, The Times? Silence in journalism is not golden. It makes a travesty of the mission to inform the public.
