In his tireless global campaign to save 77-year-old media publisher Jimmy Lai from life imprisonment in Hong Kong, Sebastien Lai has not seen his father for more than four years.

Sebastien, who leads the #FreeJimmyLai campaign, last saw his father in August 2020 — weeks after Beijing imposed a national security law that led to a massive crackdown on pro-democracy advocates and journalists. Among them Lai, founder of the now-shuttered pro-democracy newspaper Apple Daily.

After nearly four years in Hong Kong’s maximum-security Stanley Prison and multiple delays to his trial, the aging British citizen was due to take the stand for the first time on November 20 on charges of sedition and conspiring to collude with foreign forces, which he denies.

Lai, who has diabetes, routinely spends over 23 hours a day in solitary confinement, with only 50 minutes for restricted exercise and limited access to daylight, according to his international lawyers.

The United Nations Working Group on Arbitrary Detention has found that Lai is unlawfully and arbitrarily detained and British Prime Minister Keir Starmer has called for his release.

Responding to CPJ’s request for comment, a Hong Kong government spokesperson referred to a November 17 statement in which it said that Lai was “receiving appropriate treatment and care in prison” and that Hong Kong authorities “strongly deplore any form of interference.”

In an interview with CPJ, Sebastien spoke about Britain’s bilateral ties with China, as well as Hong Kong — a former British colony where his father arrived as a stowaway on a fishing boat at age 12, before finding jobs in a garment factory and eventually launched a clothing retail chain and his media empire.

What do you anticipate when your father takes the stand for the first time?

To be honest, I do not know. My father is a strong person, but the Hong Kong government has spent four years trying to break him. I don’t think they can break his spirit but with his treatment they are in the process of breaking his body. We will see the extent of that on the stand.

Your father turned 77 recently. How is he doing in solitary confinement?

The last time I saw my father was in August of 2020. I haven’t been able to return to my hometown since and therefore have been unable to visit him in prison. His health has declined significantly. He is now 77, and, having spent nearly four years in a maximum-security prison in solitary confinement, his treatment is inhumane. For his dedication to freedom, they have taken his away.

For his bravery in standing in defense of others, they have denied him human contact. For his strong faith in God, they have denied him Holy Communion.

We have seen governments across the political spectrum call for Jimmy Lai’s release —the U.S., the European Parliament, Australia, Canada, Germany, and Ireland, among others. What does that mean to you?

We are incredibly grateful for all the support from multiple states in calling for my father’s release. The charges against my father are sham charges. The Hong Kong government has weaponized their legal system to crack down on all who criticize them.

You met with the U.K. Foreign Secretary David Lammy recently, who said Jimmy Lai’s case remains a priority and the government will press for consular access. What would you like to see Prime Minister Keir Starmer’s government do?

They have publicly stated that they want to normalize relationships with China and to increase trade. I don’t see how that can be achieved if there is a British citizen in Hong Kong in the process of being killed for standing up for the values that underpin a free nation and the rights and dignity of its citizens.

Any normalization of the relationship with China needs to be conditional on my father’s immediate release and his return to the United Kingdom.

Your father’s life story in many ways embodies Hong Kong’s ‘never-give-up’ attitude. Do you think Hong Kong journalists and pro-democracy activists will keep on fighting? What is your message to Beijing and the Hong Kong government?

I think most of the world shares his spirit. Hong Kong is unique because it’s a city of refugees. It’s a city where we were given many of the freedoms of the free world. And as a result, it flourished. We knew what we had and what we escaped from.

My message is to release my father immediately. A Hong Kong that has 1,900 political prisoners for democracy campaigning, is a Hong Kong that has no rule of law, no free press, one that disregards the welfare of its citizens. This is not a Hong Kong that will flourish.
