A social media push for Cardinal Robert Sarah to become the next pope appears to be gaining momentum in the wake of the death of Pope Francis.

What are described as “neatly packaged sound bites” are circulating rapidly around conservative social media spheres of influence, reports the Daily Telegraph.

It describes how this appears to be having an impact, at least in terms of the betting markets, which have seen Cardinal Sarah's odds change significantly from just a 2 per cent chance at becoming the next pope, to the British betting company William Hill quoting him at 14/1, making him the "seventh favourite" in betting terms.
