Novichok victim Dawn Sturgess will be buried without pallbearers tonight NZT and her coffin will already be in place when mourners arrive, as a number of safety measures are put in place to protect the public.
The mother-of-three will be cremated in Salisbury, close to where Russian former spy Sergei Skripal's wife and son were laid to rest, the Daily Telegraph reports.
Public Health England have been liaising with the funeral directors to prevent possible contamination, the vicar taking the service, the Rev Philip Bromiley, told the Telegraph.
"It is part and parcel of the advice to make sure everyone attending is as safe as possible," he said. "I have every confidence that Public Health England and the crematorium know what they are doing.
"I am assuming it [the coffin] will be transported in somehow," he added, but said he did not know whether special protective clothing would be worn by those carrying it in.
Bromiley described Sturgess as a "compassionate person" adding she "would do as much as she could for everyone, sometimes even to her own detriment".
Her boyfriend, Charlie Rowley, who was found unconscious alongside her last month after coming into contact with the agent, will attend the service but is not due to speak.
The address will be given by the Rev and Sturgess' sister, Stephanie, will give a eulogy on behalf of the family.
"The basic service has been inspired by Dawn's daughter who attends one of our church schools. Her favourite song and hymn is Shalom Shalom May Peace Be With You," said Bromiley.
"That word Shalom means peace and that peace has sort of permeated through the whole service really.
"We will be using as a reading of Jesus calming the storm from Mark's gospel and thinking about Jesus bringing peace and calm to a rather chaotic situation here."
He added: "I will be praying that the Jesus who calmed the storm 2000 years ago is able to bring some sort of peace and perspective today as well.
"I will be hoping that that peace won't just be for the family but for the city and that we will be able to return to a sense of normality. Hopefully businesses will grow in confidence and be rejuvenated and we will be able to get back to how we were."
The family have chosen James Blunt's Beautiful Dawn as an introduction which Bromiley described as "hugely important".
"I think the family are really keen to celebrate Dawn and to remember that she was such a friendly, kind and compassionate person who would do as much as she could for everyone, sometimes even to her own detriment.
"She was a spiritual person; she wouldn't pass the cathedral without lighting a candle a saying a prayer. So it is appropriate we do this in a Christian context."
A spokesman for Public Health England declined to comment on arrangements for the funeral, saying it was a private occasion.
"Our advice remains the same. The risk to the public remains low," he told the Telegraph.
