It's a jungle out there

There'll be discreet whoops of joy in the BBC1 scheduling office this morning. An average of 11.12m watched the Strictly semi-final; 10.36m watched the finale of Blue Planet II; and tagging an elephant and Attenborough on to the sequence scored 4.88m.  And so, the ITV's take on the natural world, I'm a Celebrity, finished its 2017 season with an average of 9.22m, down from 10.5m last year.
