Well, you could always watch London Today/Tonight/Tonight instead, as you may already do. I don't personally because there's too much of the L-word on it, but each to their own, I suppose.
TVT isn't a complete mess. Wesley Smith's extremely competent (he was back on the lunchtime bulletin today so - no - he hasn't left) and Simon Parkin makes a decent weather presenter (is he the first weatherman not to wear a tie regularly btw?). But Chris Maughan and David Reilly are no Wesley stand-ins, but are reasonable on the Sport, as is Victoria Bennett. Mary Green's bearable: she's better than she was on Meridian Tonight, although I put that down to the Wesley effect. Unlike Hannah Shellswell, who I find hugely irritating.
In the case of Meridian Tonight being "poor" - yes, I agree with you regarding the old West edition and, as has been discussed already on the South/South East thread, recently the South East edition, too. The South edition, however, is still very professional, with two of the longest-serving regional presenters on there. And, without the faux chumminess of South Today.
