Now, to the royal couple in the middle of a blockbuster tour in asia. After overwhelming reception in the solomon islands today. All of this, after an italian magazine is going to print topless photos of kate. Abc's dan harris joins us more with this ongoing -- we're now talking three publications in three countries. Yes, it is spreading. And they're trying to stop that. And in so doing, they're taking a very rare legal stance here. The royals are taking, and this is a reflection of their outrage, they're not only launching a civil lawsuit, but they're also now pushing for criminal charges. Reporter: Hours from now, will and kate's lawyers will try to convince french prosecutors to pursue criminal charges for breach of transpassing.

The royal team is also trying to get an injunction blocking the release of any more photos of the magazine owned by civil veoh berlusconi. I think the fact that they've had such a speedy response really speaks volumes about how passionately william feels about putting an end to this type of goss imjournalism. Reporter: But they could not stop the lease of even more pictures today. A 26-page spread hitting italian new stands in a sister magazine. On twitter the editor of that italian magazine said not even a direct call from the queen could stop him.

While the scandal is certainly still boiling, you can see them traveling village to village, street to street, to talk to people on this tour for the queen. What is exactly going through their mind I don't think we'll ever know. I think william, he's looking to the future. He has said it's absolutely his number one concern to prevent a similar fate that diana experienced happening to kate. One more note on that italian magazine running the 26 pages of pictures today. This is the same magazine that published pictures of diana dying in that tunnel in paris after that car crash with the paparazzi. Dan, thanks so much. Let's bring in our legal analyst dan abrams.
