The Spanish royal family arrives for the parade to celebrate the armed forces Sunday.

It marks the last formal appearance of Spanish King Juan Carlos before his abdication.

It was announced recently that his son, Prince Felipe, would succeed him after June 18.

The future King of Spain was accompanied by his wife Princess Letizia.

Juan Carlos has spent almost 40 years on the throne.

His popularity has waned in recent years amid allegations of corruption.

Polls show greater support for Felipe.
