On this anniversary there is indeed world wide news reportage.

In the UK

the Lead item of News at Ten was the McCann documentary!

'Tuesday's News at Ten (ITV1) led on the McCanns and how they felt last August when they were named aguidos in the investigation into the disappearance of their daughter.
We already knew that the McCanns were aguidos, of course, so the news - the biggest story of the day according to Sir Trevor and the team, bigger than petrol prices, or the housing market, or Austria, or Ken v Boris - was that Kate McCann says she felt "angry" and Jerry found it "surreal" when they became people of interest to the inquiry.
Bong: Kate McCann was angry last summer.
Bong: petrol's £5 a gallon.
Bong: the horrid Austrian man is definitely both father and grandfather to lots of kids.'

quote from
Last night's TV The Guardian Thursday May 1

'Time' notes....

'with Saturday marking the first anniversary of the 4-year-old's disappearance from her family's vacation apartment in the Portuguese resort town of Praia da Luz, the ongoing media circus is again revving into overdrive. ....

Indeed, it has already begun. A two-hour television documentary about the girl's parents, Gerry and Kate McCann, was broadcast nationally last Wednesday night. It accorded sympathetic treatment to the McCanns, who remain official suspects in the investigation...

...Mark Williams-Thomas is a former detective who's now a regular consultant to various media outlets. He says police working the case in Praia da Luz "are in no rush to lift the arguido status." ...

Williams-Thomas says, it's doubtful the crime will ever be solved, unless Madeleine's body is discovered. He also doubts the police have evidence to charge the McCanns with murder. But, he says, it is likely they will be charged with child neglect, an accusation the McCanns reject.'


Myself, I can only sadly echo the comments from
'Anorak' (Tabloid news for broadsheet readers)

'The parents, friends, police and above all else the media have failed Madeleine McCann.'
