The actor Stewart Bevan, who has died aged 73 after a short illness, was a welcome presence on British television over the years. A fresh-faced juvenile lead, later a reassuring and genial character player, he gave solid performances that were grounded in reality but not without flair.
He featured in the long-running series Doctor Who, in 1973’s The Green Death, remembered fondly by viewers as “the one with the giant maggots”. The departure of popular companion Jo Grant (Katy Manning) called for someone special to lure her away from third Doctor, Jon Pertwee, and to this end the charismatic Welsh eco-warrior Professor Clifford Jones was conceived.
