I confess that I am completely bewildered by this. I found earlier an article on line as reported in my post. (Oh yes I did!) A repeat search has failed to turn it up again, however, and I am left wondering if it has been deleted meantime. What I did find however was that on 4 September 1955, Kenneth Kendall became the first newscaster to appear on a British television screen in the flesh. Which would imply that Richard Baker was merely a voice over in 1954 when he started broadcasting the news. In view of this I withdraw my previous posting, with apology.
