One doesn't expect a sitcom at this time of year to revolve around a plot to assassinate the Queen, especially one starring Sir David of Del Boy. But The Royal Bodyguard - which marks his return to BBC comedy after several austere years on t'other side - does just that, albeit in the most inoffensively silly way.

His titular security ace is a Clouseau-esque incompetent utterly convinced of his superior prowess; hardly an original creation, but Jason plays him with his usual aplomb. And you get the sense that he's really enjoying playing comedy again. But at 71, watching him take constant pratfalls - despite the understandable use of doubles at times - can be more worrying than funny: the latterday Norman Wisdom effect.

But I can't deny the appeal of this cheerfully basic slapstick farce from the writers behind The Worst Week of My Life, which exists purely to make its audience laugh and nothing more. Its very predictability is part of the gag, although it remains to be seen whether it can sustain over a series.

Incidentally, the only thing he doesn't fall through in episode one is a bar-hatch. But there's still time yet. Come on, Dave, just for old time's sake.
