David Cameron sends birthday greetings to HRH The Prince of Wales as he celebrates his 70th birthday:

“One of the privileges of my time as Prime Minister was working with His Royal Highness the Prince of Wales.

“During all the engagements, events and meetings we shared, I saw up close his sheer dedication to public service. In any spare moment, the Prince is rarely without a pen in his hand and paperwork in front of him. His work ethic is remarkable.

“I saw as well as his passion – his prescience. Tackling climate change. Protecting biodiversity. Creating a built environment that helps communities thrive. Giving young people the opportunities they deserve. These are some of the biggest challenges of our times, and they’re the things Prince Charles has been championing for decades.

“I also saw what a fun and kind couple the Prince and the Duchess of Cornwall are – completely devoted to their family, like all proud parents and grandparents across the country. Samantha and I enjoyed spending time with them immensely.

“Everything Prince Charles does demonstrates his enduring commitment to our country, Commonwealth and planet. I join everyone from across those realms today in wishing His Royal Highness a very Happy 70th Birthday.”
