This from The Street of Shame...
Yesterday Network Rail sent an e-mail to the trade press hacks headed:
INVITATION: Network Rail preliminary results media dinner June 8, 2010
It contained details of the venue for the event, invitations for which had been sent out some time ago
It said:
The dinner will be held on the evening of June 8, from 7pm
Sadly the original invitation stated the do was on Thursday 10 June.
Perhaps relying on the Integrated Train Planning System for media events was a touch over-optimistic?
UPDATE: This from The Archer...
Perhaps the dinner tonight is the preliminary results dinner and Thursday is the dinner for the preliminary results?
