Some two million people are expected
to join nationwide protests in South Korea to demand the resignation of
President Park Geun-hye, organisers say.
| Last Saturday, protesters chanted 'Park Geun-hye resign' as they waved candles in Seoul |
| The scandal is centred on the close relationship between Ms Park and Ms Choi |
The fallout from the scandal shows no sign of abating, with South Korea witnessing the largest protests since pro-democracy demonstrations of the 1980s.

- S Korea's President Park 'heartbroken'
- A friendship too far in Seoul?
On Saturday, members of the Korean Peasants League, the country's largest farmers group, are expected to join the protest in Seoul.
The farmers had wanted to bring 1,000 tractors and other machinery near the government quarter - but were banned from doing so by a court order. Local media reported scuffles on Friday, as police blocked groups of farmers trying to enter the capital in their vehicles.
But they were allowed to continue on foot to join Saturday's rallies. The organisers said as many as 500,000 people attended a peaceful candlelit rally in the capital last weekend, bringing streets to a standstill.
Police put the figure far lower.
