This is the hilarious moment when a Croatian human rights activist's trousers fell down as he was receiving an award from the country's president.

Ivan Zvonimir Cicak, who is head of the Croatian Helsinki Committee for Human Rights, was receiving an award from the nation's president Kolinda Grabar-Kitarovic when his trousers malfunctioned.

Just has he was being handed the large award, Cicak's trousers disappeared from his waist and ended up slumped around his ankles.

Mr Cicak quickly bent over to pull up his trousers as President Grabar-Kitarovic moved diplomatically to preserve the human rights chief's dignity as he readjusted his clothing following the wardrobe malfunction

Luckily, Grabar-Kitarovic was holding a large award in her hands which slightly helped preserve Cicak's dignity.

She did not appear to react, remaining calm despite a brief glance downwards and a smile as he stooped to pull them back up.
