Speaking to the BBC before her arrest in 2022, Chow said she was "prepared to be arrested"

Three Hong Kong activists who organised annual vigils commemorating Beijing's 1989 crackdown on Tiananmen Square protests have been handed prison sentences of up to seven years.

Two of the defendants - Lee Cheuk-yan, 69, and Chow Hang-tung, 41 - were convicted last month of inciting others to subvert state power, under the city's controversial national security law.

A third defendant, Albert Ho, 74, had pleaded guilty in January.

For years, Hong Kong was one of the only places in Chinese territory where people could hold gatherings to mark the Tiananmen Square crackdown - a topic that is highly sensitive and heavily censored in mainland China.

These gatherings were banned by Hong Kong's authorities in 2020, citing Covid-19 policies, but never resumed. That same year, the national security law, which makes illegal a wider range of dissenting acts, officially came into force.

Authorities say the law is necessary to maintain stability, but critics argue it has eroded Hong Kong's autonomy and created a climate of fear.

Lee, Chow and Ho were charged in 2021. They faced up to 10 years in prison after their conviction.

On Friday, the court sentenced Lee to seven years in prison, while Chow was handed seven years and three months. Ho, who pleaded guilty, was sentenced to five years in prison.

As the court session started, Chow and Lee stood up and smiled at the public gallery, which was full of people. Ho wore a serious expression.

After their sentences were handed down, Lee appeared to pray as he was led out of the dock, while Chow blew a kiss to those seated in the public gallery.

According to a court summary in August, Lee and Chow had "incited other persons to organise, plan, commit or participate in acts by unlawful means with a view to subverting the state power".

Chow told the court in May the law itself was on trial.

A key part of the trial concerned the group's slogan of "ending one-party dictatorship", which the court said had incited people to undermine the Chinese Communist Party.

Lee's wife, Elizabeth Tang, told Reuters that it was a "sad day" for her.

"I cannot imagine that he has to spend another three years in jail, it is really unacceptable," she said, adding that Lee intended to appeal his sentence.

Chow's mother Medina told a crowd outside the court not to be "overly saddened" about the verdict. "Do not lose heart. And above all, do not feel guilty," she said, Reuters reported.

Speaking to the BBC before her arrest in 2022, Chow said she was "prepared to be arrested" and "willing to pay the price for fighting for democracy".

People in Hong Kong used to hold yearly vigils commemorating Beijing's 1989 Tiananmen Square crackdown

The defendants were leaders of the now-disbanded Hong Kong Alliance, a group founded in May 1989 to support students holding pro-democracy rallies.

Weeks later, the Chinese Communist Party sent troops and tanks to crush pro-democracy protests in Beijing's Tiananmen Square. Estimates of the death toll range from a few hundred to many thousands.

Over the next three decades, the Hong Kong Alliance called on authorities to accept responsibility for the crackdown, free dissidents and introduce democratic reform.

The group also held yearly vigils commemorating the Tiananmen Square crackdown. Organisers said some of the gatherings attracted more than 100,000 people, though police had lower estimates of the turnout.

On Friday, the court also handed a HK$1.5m fine ($191,000; £142,000) to the Hong Kong Alliance.

"This sentencing is a triple tragedy: for the activists being unjustly punished; the survivors and victims of the Tiananmen crackdown itself; and the generations of Hongkongers denied the space to discuss one of the most consequential events in modern Chinese history," said Amnesty International's Deputy Regional Director Sarah Brooks.

"The harsh sentences against peaceful Tiananmen vigil organisers expose the cruelty and insecurity of a government afraid of memory and the people," Human Rights Watch said in a statement.
