For nearly fifteen months, Evan Gershkovich has been locked away in a Moscow jail.

Today the Wall Street Journal (WSJ) reporter went on trial a thousand miles from the Russian capital in Yekaterinburg: the city where he was arrested on espionage charges while on a reporting trip for the Wall Street Journal.

We were among the group of media allowed into a courtroom to see him before the start of proceedings at the Sverdlovsk Regional Courthouse.

Head shaven, and wearing a check shirt and jeans, Mr Gershkovich stood in the metal and glass cage known in Russian courtrooms as “the aquarium”. He smiled to cameras, but made no comment.

After a few minutes we were asked to leave the room. From this point on this trial will be held behind closed doors.

Prosecutors claim that the American journalist had been collecting classified information about a Russian tank manufacturer near Yekaterinburg on behalf of America’s Central Intelligence Agency.

Mr Gershkovich, his employer and the US government vehemently reject the charge. If convicted the maximum possible sentence is twenty years in prison.

The White House said Russia was using Mr Gershkovich as a “bargaining chip”.

“Evan is not a spy,” National Security Spokesman John Kirby said.

“This is a bogus process. It’s outrageous and outlandish,” believes Deborah Ball, deputy world coverage chief for Europe, Middle East and Africa at the Wall Street Journal.

“[Evan] will not enjoy any of the due process that we would expect in any Western court. It will be closed door. It will be secret.

“Russia’s acquittal rate is less than one percent. We don’t expect any chance of him being acquitted.”

In a statement on Wednesday, the journalist’s family called the past 15 months “extraordinarily painful”.

“We’re deeply disappointed that he will have to endure further attempts to discredit him and to paint a picture that is unrecognisable to anyone who knows him,” they said.

On the streets of Yekaterinburg, there is little hint of the drama that unfolded here on 29 March 2023. Russians stroll past the steakhouse where Evan Gershkovich was detained by Russian security agents. Across town people sit outside playing chess, as trams rumble by.

The WSJ has accused Moscow of “stockpiling Americans” in Russian jails to be traded for Russians imprisoned abroad.

The list of US citizens currently in prison in Russia includes former marine Paul Whelan. In 2020 he was convicted of espionage and sentenced to 16 years in a penal colony.

Mr Whelan vehemently denies having committed any crime.

Last year, Alsu Kurmasheva – a journalist with Prague-based Radio Free Europe/Radio Liberty (RFE/RL) – was arrested in Russia. Ms Kurmasheva holds American and Russian passports.

On a trip home to visit her ailing mother, she was detained. She was charged with spreading “false information” about the Russian armed forces over a book she had helped to edit which contains criticism of Russia’s invasion of Ukraine.

If convicted, she could face up to 15 years in prison.

Among the other Americans behind bars in Russia are:

• Mark Fogel, a former teacher at the Anglo-American School of Moscow, which has now closed. He is serving a 14-year sentence for drug smuggling after 17g of marijuana were found in his luggage at Moscow airport. He claims he was using the drug for medical purposes

• Gordon Black, a US staff sergeant, sentenced by a court in Vladivostok to three years and nine months in a penal colony on charges of theft and threatening to kill his girlfriend.

When he has spoken publicly about the case of Mr Gershkovich, Russian President Vladimir Putin has indicated he is open to the idea of a prisoner swap. There have been contacts between the US and Russia.

But whom does the Kremlin want in exchange?

President Putin has not named names. But he has dropped a strong hint. When asked about Mr Gershkovich a few months ago, the Russian president alluded to the case of Vadim Krasikov.

Believed to be a Russian agent, Mr Krasikov is currently serving a life sentence for murder in Germany.

“It’s evident that this is hostage diplomacy,” says Deborah Ball.

“The Russians have been perfectly plain about what their objective is. Putin has barely hidden the fact that he wants to trade Evan and regards him as a pawn. He’s a political hostage.”

The Kremlin knows that America makes deals to get its citizens back. In 2022, the US authorities released a convicted Russians arms dealer, Viktor Bout, to secure freedom for Brittney Griner. The American basketball star had been jailed in Russia on drug charges.

Now an American journalist is in the dock.

The Kremlin declined to comment on talks over a possible prisoner swap deal with the US.

Kremlin spokesman Dmitry Peskov said that he could not go into detail and that the topic should not be publicly discussed.

“The investigation is under way, the trial is under way, so here we just need to wait for the verdict that will be delivered,” he said.

It is unclear how long the trial of Evan Gershkovich will last and how much longer the US reporter will be in a Russian prison.

“It’s impossible for us to read this. We just don’t know, we’re shooting in the dark,” says Ms Ball.

“The Russians regard this process, this sham trial, as part of some process they envision. Where it fits into what happens next, we have absolutely no idea.”
