Queen Beatrix of the Netherlands to abdicate for son

Queen Beatrix announced her abdication in a nationally televised address

Queen Beatrix of the Netherlands has announced she is abdicating in favour of her son, Prince Willem-Alexander.

In a pre-recorded address broadcast on TV, she said she would formally stand down on 30 April.

The queen, who is approaching her 75th birthday, said she had been thinking about this moment for several years and that now was "the moment to lay down my crown".

Queen Beatrix has been head of state since 1980, when her mother abdicated.

In the short televised statement, the queen said it was time for the throne to be held by "a new generation", adding that her son was ready to be king.

Prince Willem-Alexander, 45, is married to Maxima Zorreguieta, a former investment banker from Argentina, and has three young children.

He is a trained pilot and an expert in water management.

He will become the Netherlands' first king since Willem III, who died in 1890.

Speaking on television immediately after the abdication announcement, Dutch Prime Minister Mark Rutte paid tribute to the queen.

Queen Beatrix is seen by many in the Netherlands as a surrogate grandmother. Most office buildings and universities proudly display her glamorous portrait, decorated in a range of suitably colourful costumes.

She enjoys high approval ratings and is one of the most popular ruling monarchs in Europe. Under Dutch law it is still illegal to insult the queen.

Her abdication is bound to raise interest in the UK, where Queen Elizabeth II is 86 and recently celebrated her Diamond Jubilee. But the situation is different in the Netherlands, where the queen is following recent tradition by abdicating, as her mother and grandmother did before her.

Prince Willem-Alexander's wife, Maxima, is arguably the most attention-generating member of the Dutch royal family. She is expected to be given the title Queen Maxima.

The queen will hand over to her son on Queen's Day on 30 April - already one of the biggest and most raucous celebrations on the Dutch calendar.

"Since her coronation... she has applied herself heart and soul for Dutch society," he said.

Abdication 'tradition'

Queen Beatrix is the sixth monarch from the House of Orange-Nassau, which has ruled the Netherlands since the early 19th Century.

Correspondents say she is extremely popular with most Dutch people, but her abdication was widely expected and will not provoke a constitutional crisis.

Under Dutch law, the monarch has few powers and the role is considered ceremonial.

In recent decades it has become the tradition for the monarch to abdicate.

Queen Beatrix's mother Juliana resigned the throne in 1980 on her 71st birthday, and her grandmother Wilhelmina abdicated in 1948 at the age of 68.

Queen Beatrix will be 75 on Thursday.

She has remained active in recent years, but her reign has also seen traumatic events.

In 2009 a would-be attacker killed eight people when he drove his car into crowds watching the queen and other members of the royal family in a national holiday parade.

In February last year her second son, Prince Friso, was struck by an avalanche in Austria and remains in a coma.
