Three members of the same family have died from coronavirus after meeting up on Christmas Day.
Tracy Latham's partner Darren Fisher and his parents Pat and David Fisher all died from Covid-19, Derbyshire Live reports.
The family, from Derby, who had been shielding since March, met up after the Government relaxed rules and allowed households to meet for one day only.
Boris Johnson allowed three households to form a bubble for the day after scrapping previous plans to allow five days of mixing.
Tracy, from Mackworth, now says her life has been ruined after the "horrendous" loss of her partner, 48-year-old Darren.
The pair had been due to get married in July this year after spending 12 years together, during which time Darren helped raise three of Tracy's children from a previous relationship into adulthood.
The 50-year-old mother-of-three, says Darren spent two hours with his parents and uncle in Allestree, Derbys, while she stayed at home.
That time together was enough for him and several family members to contract Covid, something she thinks would not have happened if the Government had stopped people meeting on Christmas Day.
Over the course of the following week, Darren, his parents Pat and David Fisher, aged 79 and 82, all tested positive for the disease.
All of them have now died and another of Darren's uncles, Geoffrey, who also caught the disease, is still recovering after becoming seriously ill.
Tracy says the only member of the family who had an underlying health condition was Pat, who had diabetes.
Tracy, who is unable to work because of a long-term health condition, says she has been left devastated by the passing of four close family members in such a short space of time.

She told Derbeyshire Live: "Darren's mum said 'we've got my brother coming over' as they had all been shielding."
"Darren popped in to them for a couple of hours to say hi, as they hadn't seen each other for ages. It was a quick flying visit at around 9pm."
Things began to go wrong when Pat, who fell and hurt her leg on Boxing Day, was admitted to the Royal Derby Hospital on December 27.
Tracey added: "She began to feel tired and rundown.
"A few days later, she tested positive for coronavirus as her condition got worse."
Pat's positive test result came through just days after arriving at hospital, ruling out the possibility of her catching it on the ward.
Meanwhile things got worse when Darren began to display symptoms of the disease and began to 'struggle to breathe' and the family rang an ambulance on December 29.
Tracy said: "On the Friday I got a phone call from Darren to say they were going to put him on a ventilator.
"I told him to get himself right, and those were the last words I said to him.
"He was on the ventilator for nine days.
"At one stage it looked really bad and they said I need to come in and speak to him. I was there saying 'you really need to fight this'."
What Darren wouldn't have known at that point is his mum and dad had already died from the virus, with David dying on January 4 and Pat dying on January 6.
Tracy said: “He was on the ventilator for nine days. His uncle is in the next bay along at the same time.”
Sadly Darren did not recover, and died on January 11. His uncle died two days later.
Pat, Darren and his uncle all died at the Royal Derby Hospital in the space of a week while David, who had dementia, passed away at a respite home he had been placed in while Pat was in hospital.
David tested positive for Covid after he died and Tracy believes he is the person who passed it onto Geoffrey, who went round to help him while Pat was in hospital.
A date for their funerals has not yet been set, with arrangements being put on hold until Geoffrey is well enough to organise them.
Tracy said she wishes Boris had never relaxed the rules.
She added: "I wish that Boris had said nobody could visit each other at Christmas.
"Then to stand up and say I'm sorry for all those lives that have been lost, he hasn't got a clue.
"The Government hasn't done enough - the lockdown was too little too late.
"That's not going to bring my loved ones back."
For now Tracy is left thinking of the wonderful memories she had with Darren and his parents.
She said: "He helped me bring my three kids up for 12 years.
"He had worked at Sainsbury's for 18 years and people would always say he had a smile on face.
"They were a lovely family - the best mum and dad you hope for. Their door was always open for you. There were a complete Derby family and so kind.
"Darren was a Derby County fan, it was his life. He went to every game he could with his friends and he loved watching the darts."
She has a stark stark warning for people who she thinks aren't taking the pandemic seriously.
"We are just all shocked and devastated," Tracy said.
"Please, you really need to take this seriously. Darren's mum and dad shielded for nearly a year and thought they were safe and well.
"It shows it can happen to anybody in the blink of an eye."
