The overnight viewing figures show that 5.77 million (29.4% share) tuned in for "The Husbands of River Song".
"Downton Abbey" was the most watched show with 6.88 million - BBC1's highest rated show was "Strictly Come Dancing" with 6.49 million. If you combine both the BBC and ITV figures for the Queen (6.1 on BBC1 and 1.3 on ITV) then it becomes the highest rated with 7.4 million.
Ratings in general are down from last year where, for instance, "Mrs Brown's Boys" achieved 7.61 million overnight last year - and this year it dropped to 6.4 million. "Doctor Who" seems to have held up relatively well with only a small drop from "Last Christmas" at 6.34 million.
Consolidated ratings will be released next week.
