Will criminal Callum Logan survive Coronation Street‘s highly anticipated hour-long live special episode which airs tonight?

Bookmaker William Hill has made the character, played by Sean Ward, the favourite to be killed off with odds of 1/8 on this outcome.

“Around 80 per cent think Callum will be killed off tonight, but there is every chance that the current storyline is a double bluff,” said William Hill spokesman Rupert Adams.

The Platt family is central to the action tonight and the odds on David (Jack P Shepherd) dying are currently a 6/1 shot, while his half-sister Sarah-Louise (Tina O’Brien) and wife Kylie (Paula Lane) are both 8/1 to be bumped off.

During the episode, which marks ITV’s 60th birthday, the Platts are caught up in a war with violent, manipulative Callum, but Sarah-Louise runs into trouble when she takes him on; what will her ex-boyfriend do in retaliation?

As befits a live episode, viewers are promised drama, comedy and tears.

A big secret is also revealed as Tim Metcalfe (Joe Duttine) finds out about the kiss shared between his fiancee Sally Webster (Sally Dynevor) and her ex-husband Kevin Webster (Michael Le Vell).

For the first time, fans will be treated to a second screen experience; they’ll be able to watch the episode being made on itv.com and Facebook via their laptop, mobile or tablet.

The stream is hosted by Stephen Mulhern, who is also presenting an after-show called Coronation Street Live: Uncovered on ITV2 at 10pm.

Coronation Street’s live episode airs tonight at 7.30pm on ITV.
