Madrid - Spain's king-in-waiting Prince Felipe vowed Wednesday to work for a “united and diverse” nation in his first public remarks since King Juan Carlos announced his abdication.

While stressing his respect for Spain's parliament, which has yet to proclaim him monarch, the prince promised to devote all his strength to serving the Spanish people and “our dear Spain - a nation, a united and diverse social and political community that has its roots in a millennium-long history.”
