Willem-Alexander becomes king after Dutch abdication

Willem-Alexander has become the first king of the Netherlands since 1890, following the abdication of his mother.

He became the country's first king since 1890 when his 75-year-old mother signed the abdication deed earlier on Tuesday after 33 years on the throne.

Huge crowds of orange-clad partygoers are in Amsterdam to pay tribute.
