Spain's Princess Cristina has become the first member of the country's royal family to be put on trial.

She is charged with being an accomplice in an alleged embezzlement scam involving her husband and 16 other defendants, who all deny the charges.

Princess Cristina, 50, faces eight years in jail if found guilty by a three-member panel of judges.

The trial in Palma, Majorca, is seen as an embarrassment for the royal family.

Princess Cristina arrived at the court in Palma on Monday with her husband, Inaki Urdangarin, who is accused of embezzlement and money laundering.

They made no statement to reporters. A small group of anti-monarchists protested outside.

As the judges read out the charges, the princess sat at the back of a makeshift courtroom at the public administration school in Palma. Her husband sat in the same row but court rules prevented them from sitting together.

t all looks so normal.

Three rows of six defendants sitting in court on blue chairs, facing the panel of judges.

But in the third row, at one end, sits Princess Cristina, sixth in line to the Spanish throne.

It's something many people in Spain thought they would never see - the powerful being held to account.

Princess Cristina's lawyers will try to get charges against her dismissed. But in a country where corruption has become a huge political issue, this is a big moment.

Mr Urdangarin's supposedly non-profit Noos Institute sports foundation was allegedly used as a vehicle to win falsely inflated contracts from regional government bodies, before channelling the money to personal accounts via tax havens.

Noos is alleged to have received more than €6m (£4.4m; $6.5m) of public money, most of it from the Balearic Islands and Valencia regional governments.

If found guilty, Mr Urdangarin could face 19 years and six months in jail.

Princess Cristina was a board member at the foundation and, with Mr Urdangarin, co-owned a real estate company called Aizoon, which prosecutors say was used to launder embezzled funds.

The case was launched in 2010 by a judge investigating corruption among Balearic Islands officials. It has become highly symbolic of perceived corruption among Spain's elites, including the royal family.

As the trial began, the princess's lawyer asked the judges to drop the case against her because it was not supported by public prosecutors.

Her defence argued that the only accusation against the princess had been made privately, by anti-corruption group Manos Limpias (Clean Hands). Lawyers cited the so-called "Botin doctrine", named after a case dropped against a former Spanish bank chief in 2007.

But Clean Hands lawyer Virginia Lopez Negrete argued that the private case had just as much legitimacy as the public prosecution.

Last year, King Felipe stripped his sister of the title of Duchess of Palma, but she remains sixth in line to the throne.
