With such inaccuracy (presumably taken from his CV), the committee is sure off to a good start.
Even Manchester Airport, in its own Report and Accounts, makes the rather more modest claim that when the parallel runway was opened in 2001 it was
"the first full-length runway built in the UK for commercial use for over 20 years".
Still, he wouldn't be the first person to embroider his CV.
In a previous discussion on this topic here

LSG6753 helpfully pointed out that the Government has in the past used 3000m+ as the criterion for defining a "full-length" runway.
