If Leslie Grantham could possibly drag himself away from his more interesting private life and put a bit of effort into his lines, I'd like to see him stay. However since his return from panto, he's been looking boring sh*tless, so I won't be that sorry to see him go (if he does).
The one thing I can't bear is the thought of yet ANOTHER bl**dy halfwitted attempt by the scriptwriters at writing a character out. Hmm, let's see... Off to set up a bar in Spain (Shaz is leaving, they could go together). Fitted up for a murder, on the run, keeping a rapist's baby (well he returned from the dead so a male pregnancy isn't out of the question) or the ever reliable, 'Anyone seen Den, can't think where he's got to, oh well let's never mention it again'.
If he has been caught as alleged on Digi-cam, then he should surely know, no one is beyond getting caught & getting sacked
