Now unless the government have been testing a new plane, I guess that wind
might be to blame for this.

I am a little puzzled why you find it weird.

I would guess that you were looking NW and the trailing aircraft did a
routine turn over the Newcastle VOR (radio beacon) and then set heading for
his next point (perhaps the Talla VOR or maybe Glasgow)

The thinning of the trail at the 'kink' is probably simply a coincidence
that the aircraft happened to pass through a patch of less moist air at the
very point it made its turn. Straight contrails often have gaps/thinning
for this reason.
