On another thread it was mentioned that Madeleine spending Christmas alone with her grandmother may have been the catalyst for this question from the PJ.
41 --- Asked whether or not it is true that in England she was thinking to deliver MADELEINE into the custody [guardianship] of a family member, she did not respond.
This assumption seems to have come from an interview in the Daily Record with Madeleine’s Scottish grandmother in which she said
“When she was two, Madeleine spent Christmas at my house and it was lovely.
"The next year, the family came up for New Year but on Christmas Day Madeleine called and said she'd got a kitchen from Santa. She was very excited and said 'I'm going to make some tea'."
For me it’s obvious that Mrs McCann only mentioned Madeleine because that’s who she was specifically asked about. There is nothing to suggest that Madeleine’s parents and siblings weren’t there too.
That being said there is no way that this could have possibly been the catalyst for question 41.
