Judge John Deed Heart of Darkness (2001–2007) watch online HD

With Jo's wedding approaching, Deed pleads with her to re-consider. In court he finds himself presiding over a pre-trial hearing where a mother is refusing to allow her daughter to receive the MMR (mumps, measles, rubella) vaccine on the grounds the multiple vaccine is unsafe. It doesn't help that her husband is the principal spokesperson and advocate for child immunization. Appearing before Mrs Justice Morag Hughes, Jo Mills makes an application of habeas corpus on behalf of Rose Hussein who was arrested by the police after she publicly accused the British Army of poisoning innocent Iraqis with weapons made of spent uranium. The government is concerned at the outcomes of both cases and try their best to inhibit Deed's freedom of action and to threaten Hughes with bad publicity over her affair with Hughes.

This episode was criticised for portraying a causal link between the MMR vaccine and autism, and the BBC received complaints on the matter. The Editorial Complaints Unit ruled that the episode had contravened the BBC's "obligation of due impartiality on matters of public controversy" and that the episode would not be repeated in its original form. The episode was cited in From Seesaw to Wagon Wheel, an internal BBC report on impartiality in its output that was published in June 2007, a section of which highlighted that the name of the Westwake character bore more than a passing resemblance to that of Dr Andrew Wakefield.
