I think the VW spotted in Spain had GERMAN numberplates
Whilst it’s been reported that the suspect’s VW has PORTUGESE numberplates.
So, unless he changed the numberplates and changed them back again that summer when he was living back in Portugal (helping with the “Rehabilitation Programme” 
) it’s possible that this was just a sighting of a German tourist with his daughter.
I really strongly doubt B would brazenly take the most sought after child in the world out for meal in Spain three weeks after her disappearance.
All the same, that particular sighting did warrant investigation and it’s horrendous how all of these missing children were failed.
There are other sightings which needed further investigation too, unless they have been and information was not released to the public.
One being the four year old English child in a shop in Amsterdam with a Portuguese speaking man and an English speaking woman shortly after the abduction who told the staff member her name was “Maddie” and “This lady isn’t my Mummy. She’s a stranger. They took me from my holiday”.

Another being the Manchester based Barrister who was afraid to compromise himself but was badly shaken in 2013 after being told in detail of an acquaintance meeting Madeleine at a party in the Mediterranean in 2013. He was so disturbed by what he had been told he said he couldn’t live with himself if he didn’t notify police.

I mentioned in the last thread that CB returned to Germany with a large amount of cash and posters said this was likely to be stolen in hotels. It was a LARGE sum of money, enough for him to buy a house.
Why did he have wigs, “exotic” clothing, children’s clothing? He filmed at least three of his crimes and multiple witnesses have seen them. The police have explicitly asked for anyone who has seen the beam in his farmhouse to come forward. Why? Surely because they want details of other films that exist? The beam was used in videos of the rapes of two women/ one possibly a girl of 15.
I think there’s a distinct possibility that he was making videos to order which would explain the ages (from pensioner to child). The “rehabilitation programme” he was involved with sounds a hell of a lot like trafficking. At his kiosk business in Germany, the local school caretaker has come forward to say CB kept bags full of toys to give away as gifts to local children and boys and girls as young as 9 were regularly invited behind the counter.
He’s got past convictions for everything from burglary, to fraud to making and supplying drugs, to making images of child abuse. What do you think the odds are that he would say no to being involved in sex trafficking and abducting children to order? Especially when large amounts of cash would be involved? He’s admitted to “snatching” Madeleine, not killing her, although allegedly he has claimed she was “dead and that’s that” when people brought her up to him.
The police are clearly looking for other people in this. I doubt he is the only person involved in Madeleine’s disappearance. The more I find out about the case and the kind of twisted perverts that roam the earth the less I want to know. I’ve found it awfully upsetting and can’t imagine how the families of missing children must feel and the hell they go through.
On the subject, please if you have time take a look at the Interpol website which helps to identify people involved in the sexual abuse of children and paedophile rings. There are no images of the children or the abuse, just clothing and household objects which if identified could help track down these poor little kids and the monsters they are in the hands of.
