Secretary General of the Singapore Democratic Party, Chee Soon Juan, spoke for nearly 50 minutes. He called for greater freedom of speech in Singapore and greater transparency in government.

Chee Soon Juan: Wants more "accountability"

It was his second address in a week. On 29 December, Mr Chee attacked the government on a range of issues, including its handling of Singapore's economic problems.

After that meeting the police summoned him for an interview, but he refused to attend.

Ahead of his latest speech, he told the BBC: "If you look at the situation that's blighting this region right now, it's precisely because of this lack of transparency and accountability in government."

Afterwards Mr Chee was approached by a policeman bearing a summons. He was ordered to attend a police station later on Tuesday where he was expected to be charged again with giving a public talk without a licence.

Such an offence carries a fine of up to S$5,000 (US $3,000).

Future addresses

Dr Chee has said he will continue giving public talks until the government guarantees Singaporeans the right to assemble peacefully and speak freely.

"The important thing is to be able to get the message to them and not to have the information distorted by the state-controlled media," he stated.

"Our press releases have been censored or totally ignored in very many cases and we have a situation where our right of reply has not been given."
