Think that is Peter - though by this time - and this was still when announcer went in-vis to read the local news headlines -  they would have been sitting in front of a plain grey background with updated LWT logo (see attachment for a view inside)

Towards the end, don't we also see the control room from where Channel 4 ad breaks were played out? (along with the occasional 'over on ITV' opt-out link)

Nice to see they kept a commercial copy of Fourscore...

Your photo shows Keith Harrison on duty. The previous photo from Stooky Bill is Peter Lewis. The presentation studio had a number of backdrops that could be slid into position, I think they were basically flats on a rail but it is too long ago to remember now. The ‘LWT’ logo in Stooky Bill’s screen grab does look a little odd I have say, I can’t think of any obvious reason why the ‘L’ would be missing (overlapping flats?) - there is a fair bit of reflection from the glass between the studio and the control room which doesn’t help.

Yes, the video does also show the C4 presentation area, it temporarily became the main ITV control room area for a short time whilst the LNN transmission area was built in the original ITV control room area. It took a brave projects engineer to move the GVG300 vision/sound mixer! The video does not show the C4 announcers booth which is a pity. The original ITV presentation studio had a deep  concrete floor to facilitate sound deadening, the LNN LMS machines were eventually placed on that floor which could not be removed. Channelled groves were cut into the concrete floor so that the LMS cables could run under the kit etc, I guess being concrete it helped to support and spread the considerable weight of the two LMS machines. All this was sitting above the scene dock below!
