Harald is going to have to take steps to save the Monarchy in Norway--if it's not too late. The way I see it, these are the possible scenarios:

1. Haakon and Mette Marit divorce, she agrees to keep a low profile, and she loses her styles and titles;

2. Mette Marit and Haakon remain married, but are removed from the line of succession and their styles and titles are stripped and they cannot undertake any official engagements;

3. Haakon and Mette Marit remain married, but she loses all her styles and titles and can no longer perform Royal duties.

I think 1 is the best option at this point.
