Aung San Suu Kyi registers for Burma election run
Hundreds of supporters turned out to see Burmese pro-democracy leader Aung San Suu Kyi register to run in a by-election for a parliamentary seat.
The National League for Democracy (NLD) party head will run in Kawhmu, southwest of Rangoon, in polls on 1 April.
Ms Suu Kyi was released from house arrest in November 2010.
Her party boycotted the last elections but has now rejoined the political process amid reform in Burma.
The by-election will fill 48 parliamentary seats left vacant when cabinet members and deputy ministers assumed their posts.
The NLD plans to contest more than 40 seats in the event that is being seen as a key test of the military-backed government's reformist credentials, says BBC South East Asia correspondent Rachel Harvey.Prisoners released
Ms Suu Kyi is seeking office in the rural township of Kawhmu. It was one of the areas hit hard by Cyclone Nargis, which left at least 138,000 people dead in the Rangoon region and Irrawaddy Delta in 2008.
She made no public statement as she filed registration papers but as she left the office she was mobbed by hundreds of supporters during an impromptu walkabout.
Some carried flowers, others had served long prison sentences for being members of her political party.
The by-election will almost certainly see her take a seat in Parliament, and her party, the National League for Democracy become the official opposition, says the BBC's Jon Williams, in Rangoon.
Kawhmu hardly seems prepared for the wave of election fever that is about to sweep over it.
The township is a sleepy rural community with a couple of traditional tea shops, a motorbike repair garage and a street food market.
The local NLD branch office is made out of bamboo and water is drawn from a well outside.
But this is the constituency in which Aung San Suu Kyi has chosen to run, the first time ever she has stood for public office.
The real test for Aung San Suu Kyi and the NLD could be managing the expectations of their supporters, some of whom are impatient for change, he adds. It could be 2015 before the next general election in Burma.
The by-election will be the first time that Ms Suu Kyi will participate in an election. She was under house arrest in 1990 when her party, the National League for Democracy (NLD), won the election by a landslide. It was not allowed to take power.
The NLD boycotted the 2010 election that saw the military-backed civilian administration of President Thein Sein replace the military junta.
The new administration has since entered into dialogue with Ms Suu Kyi and changed the electoral laws that led the NLD to boycott the 2010 polls.
Last week the government signed a ceasefire deal with Karen rebels - who have fought for greater autonomy for more than 60 years.
It also released many political prisoners on 13 January, including Burma's most prominent political dissidents - 88 Generation Student leaders Min Ko Naing and Ko Jimmy, as well as Buddhist monk Shin Gambira.

The US has described the release of political prisoners as a substantial step towards democratic reform and says it will start the process of exchanging ambassadors with Burma.
Burma remains the subject of economic sanctions from the European Union, the United States and Canada, among others. Of the major economies, only China, India and South Korea have invested in the country.
But Western leaders have said they will match progress towards democracy in Burma with concessions and political incentives.
The Philippines - one of the most outspoken critics in Asia of Burma's military rule - has also reiterated its call for the lifting of sanctions on Burma, citing "unprecedented political and economic reforms" towards democracy.
Both countries are members of the Association of South East Asian Nations, which Burma will chair in 2014.
