I wouldn't be surprised if part of the revamp was the return of Alastair Stewart to presenting the 6pm programme (in addition to his national duties).
That way they can mask the extent of the cuts by dressing up the revamp as the return of the presenter most closely associated with the programme over the years.
I have to disagree with you there, I doubt making Alistair return to the program is part of this shake up, the reason why they got rid of double headed presenting was because it caused so much hassle in trying to find cover. Having Robin and Lucy Cotter presenting for example doesn't really work and adds no credibility to the show. Imagine how much hassle it would be to find replacements for Alistair and the crossover between both programs wouldn't work either.
I wouldn't be surprised if the new virtual studio consists of one chair like BBC London.
As regards to Lucrezia, it is nice to see her presenting but if the whole master plan is to make her the second cover when all the changes come into place then I think it is too big a role too soon. I feel that if you are going to adopt a much greater role on the program you have to have time to develop, there is no question that Lucrezia presents well but to be given a bigger presenting role so quickly to me doesn't really work.
There also needs to be a lot more of an identity for London Tonight, in the Meridian region for example you can expect to see Fred and Sangeeta every week night at 6. As for London Tonight Nina's days are all over the place, previously you would expect a main presenter Monday - Thursday and then cover on Friday but having this mishmash creates a lot of unfamiliarity.
I just hope that any more losses at London Tonight come from people other than those who have been on the program for a long time. Like the CurrentBuns website caught on to the fact when Andrea Byrne was presenting along with a freelance report and Meridian weather presenters that viewers would question if they were watching the right program, if this shakeup at LT gets rid of familiarity then I feel that what's left of the programmes identity will diminish.
