As for Letizia's events, I'm a bit disappointed that those events are typical events for princesses or political wives: soft culture events, healthcare and children. In the past, Letizia got to attend business and political meetings with Felipe on trips. I found that more impressive than these "soft" events. So I'm not sure what the big deal it is with having solo events. I knew it would be like this.
She was in the meeting with businessmen from both countries.

I was a little disappointed she didn't go to the lunch with the PM, but having lunch with the first lady was not too bad either. Like Felipe, Letizia also knew a lot about global politics and economy, maybe that was the reason Zarzuela prefered Felipe going alone (just kidding) . The radio interview link I posted on Felipe's 40th birthday thread, the main union leaders in Spain Cándido Méndez and José María Fidalgo had openly praised Letizia on her knowledge in the same subject after an interesting discussion with the Princes at a private gathering.
