Yes he has done for the last 4 weekends or so. Its been Anita McNaught in the morning and Mike in the afternoon. In the flags era, he used to present BBC World, as well as Peter Dobbie.
It seems Mike Embley is going up in the world. Starting off in crappy Newsroom South East, he moved on to BBC News 24 and now BBC World! I don't like him much though.
