It is indeed the same Sasha Twining. As well as being one of best, imo, continuity announcers that both the BBC, then ITV had - she is also a qualified journalist. She looked very much at home in front of the camera - friendly yet authoritative. One wonders why she spent so long hiding away out of vision! On the basis of what I've seen I should imagine that one of the London based channels will be looking to employ her asap (assuming that she's only gone to Moscow to further her career of course. She might be very happy there!!)
