In honour of his 70th birthday, Finnish president Sauli Niinistö took to Twitter to thank well-wishers while posing with his young son Aaro and the nation’s favourite pooch Lennu.
The photograph marks the first public photo of young Aaro Veli Väinämö, born to Niinistö and his wife Jenni Haukio in early February this year.
In the first photo Aaro asks "Should we sing?", and in the second the president thanks well-wishers for remembering his birthday.
