Malaysian Member of Parliament Nurul Izzah Anwar was arrested on Monday under the Sedition Act for remarks she made about the country's judiciary.

There was a sense of deja vu as the 34-year-old, now an experienced politician, took the stand in parliament for her jailed father and read out parts of a speech on his behalf.

Her father, opposition politician Anwar Ibrahim, 67, was convicted in March 2014 of sodomising a former male aide and sentenced to five years in jail. The conviction was upheld by Malaysia's highest court on Feb 10. Anwar has denied the charge, calling it a "political conspiracy".

Nurul Izzah, Anwar's eldest daughter, was thrust into the limelight when her father was first accused of sodomy in 1998. Since then, there has been speculation about her political future.

Will she step into her father's shoes eventually as leader of the opposition? Here's more about Malaysia's Reformasi Princess.

1. Thrust into the spotlight at a young age

In 1998, Nurul Izzah was a bright 18-year-old going to university when her father was first arrested.

She gave interviews to the media and visited Indonesia and the Philippines to thank the leaders of the countries for publicly supporting her father.

Her mother, Dr Wan Azizah Wan Ismail, said then that she derived "so much strength" from Nurul Izzah, then an engineering student. "I could confide in her, she is old enough to understand," Dr Wan Azizah said.

Anwar was convicted of that first charge of sodomy in 1999, and sentenced to six years in jail.

2. Reluctant politician?

While she lobbied for her father in Malaysia and around the world when he was jailed from 1999 to 2004, Nurul Izzah did not formally enter politics.

She was tipped to run in the 2004 general election, but dropped the plan to focus on her final exams.

She received her first-class degree in engineering at Universiti Tenaga Nasional just as her father was released from his first imprisonment.

In May 2007, she graduated from Johns Hopkins University with a Masters in International Relations.

Up to a month before the 2008 elections, there were questions about whether she was running.

3. Reformasi Princess

At age 27 and still nursing a four-month-old baby, Nurul Izzah took part in the March 2008 Malaysia General Election that saw the ruling Barisan Nasional lose their two-thirds majority in parliament for the first time since 1969.

She ran in Lembah Pantai, an electoral district in Kuala Lumpur that includes the trendy upmarket Bangsar area, but has pockets of urban poor.

With about 53 per cent of the vote, she beat a Cabinet minister - Shahrizat Abdul Jalil, who was the Women, Family and Community Development Minister.

Nurul Izzah retained her seat in the 2013 election against another heavyweight - former Federal Territories Minister Raja Nong Chik Zainal Abidin.

She is now vice-president of opposition party Parti Keadilan Rakyat (PKR).

The photogenic Nurul Izzah has been dubbed the "Princess of Reform" by the Malaysian media. She is a fiery speaker, and some say she outshines her father.

But her connection with her father has been said to be both a boon and a bane.

While the family name and fighting for his cause has raised her profile, some wonder if now, it has become a distraction. Observers say she needs to forge an identity out of her father's shadow.

4. Siblings

Anwar and Wan Azizah have five daughters and a son, Nurul Izzah is the eldest. The other daughters are: Nurul Nuha, 31, Nurul Ilham, 27, Nurul Iman, 24 and Nurul Hana, 22. The son is Muhammad Uhsan, 29.

This year, Nurul Nuha seemed to be following in her elder sister's footsteps, but she is reportedly not the natural politician Nurul Izzah is.

All the children have been publicly supportive of their father, and have led marches demanding his release this year.

5. Marriage and divorce

In 2003, Nurul Izzah, then 23, married 26-year-old chemical engineer Raja Ahmad Shahrir Iskandar. He is a distant relative of Johor's royal family.

The two met in London in 1999 when she went to muster support for her father among the Malaysian students there. He was a student in Cambridge.

They were divorced in January 2015 and have joint custody of their two children.
