PR manager Martyn Hett is the latest person to be named as a victim of the Manchester Arena terrorist atrocity.

Martyn Hett, 29, from Stockport, is believed to have been at Monday's Ariana Grande concert with his friend Stuart Aspinall when the pair became separated.

Mr Hett's brother, Dan Hett, confirmed his death on Twitter, saying: "They found my brother last night. We are heartbroken."

Russell Hayward, believed to be Mr Hett's partner, added: "We got the news last night that our wonderful iconic and beautiful Martyn didn't survive. He left this world exactly how he lived, centre of attention.

"I'm in a really bad way so please forgive if I don't reply. Thankfully I have this wonderful family and amazing friends to keep each other strong. I love you Martyn. I always will."

Mr Hett had appeared on TV shows Come Dine With Me - which he won - and Tattoo Fixers, when the Coronation Street super-fan got a tattoo of character Deirdre Barlow inked onto his leg.

He worked as a digital manager for Altrincham PR firm Rumpus, where last week he had his last day in the office before taking two months off to travel around the US.

The company said: "Martyn loved life, he celebrated it every day and packed it to the brim with his passions.

"He taught us so much about seizing opportunities and rejoicing in everything life could offer, no matter how small, a birthday, a great moment at work, a celebrity follower, he made them special, now we know why.

"He was taken from this world too soon, by forces we will never truly understand. Our heartache goes out to his family and friends, we will miss him."

Paying his own tribute, managing director Paul Evans said staff were distraught at the loss of their "much-loved, larger than life, colourful and charismatic colleague".

He said: "Martyn was an upbeat and positive soul who saw the good, the joy, the fun in everything. He lived life to the full and loved so many things - American divas, Coronation Street, 80s fashion and the Eurovision song contest.

"His joy at appearing on - and winning - the TV programme Come Dine With Me was matched by his delight at having his Twitter account verified.

"He lived life to the full and loved sharing his antics on social media, where he had a huge following of people who loved reading his posts.

"At work, he was the consummate professional. A master of his subject - he was a talented writer, creative thinker and social media expert.

"Next week would have been the fourth anniversary of his joining Rumpus. Words really can't express how much he will be missed by colleagues and clients alike.

"Martyn loved life and I hope his lasting legacy is that people - in these dreadful times - choose to live their lives with joy not hate, just like he did."

Schoolgirls as young as eight and parents who had come to pick up their children were also among those killed in the suicide bomb attack.

The youngest person known to have died is eight-year-old Saffie Roussos, who was at the concert with her mother.

Another young victim is thought to be schoolgirl Megan Hurley.

Here is what we know so far about the victims and the missing:

Georgina Callander

Georgina, from Chorley, was in her second year of studying health and social care at Runshaw College in Leyland, Lancashire, and had previously been a pupil at Bishop Rawstorne Church of England Academy.

The college, which confirmed her death, spoke of its "enormous sadness", saying: "Our deepest sympathies, thoughts and prayers go out to all of Georgina's family, friends, and all of those affected by this loss."

Saffie Roussos

The youngest known victim of the atrocity, eight-year-old Saffie had been at the concert with her mother, Lisa Roussos, and sister, Ashlee Bromwich, who is in her 20s, from Leyland, Lancashire.

They are both now in separate hospitals being treated for injuries, friends said.

Chris Upton, headteacher of Tarleton Community Primary School in Lancashire, said: "Saffie was simply a beautiful little girl in every aspect of the word. She was loved by everyone and her warmth and kindness will be remembered fondly.

Olivia Campbell

Olivia, from Bury, Greater Manchester, was among the first of the terrorist's victims to be named.

The 15-year-old went to Tottington High School and had been to the concert with her friend, Adam, who has received treatment in hospital.

Olivia's family had spent Tuesday frantically searching for her, but in the early hours of Wednesday Charlotte Campbell revealed her daughter had died in the blast.

Alongside a photo of Olivia she wrote on Facebook: "RIP my darling precious gorgeous girl Olivia Campbell taken far far too soon go sing with the angels and keep smiling mummy loves you so much."

John Atkinson

Mr Atkinson, 26, from Radcliffe, was named by friends on Facebook as a victim.

A fund for his family set up by friends has raised around £5,000

Hayley Turk, who organised the fund through website GoFundMe, wrote: "John was one in a million and loved by so many. A true gentleman."

Martyn Hett

The 29-year-old PR manager, who had appeared on TV shows Come Dine With Me and Tattoo Fixers, was killed days before leaving for a two-month trip to the US.

Mr Hett's brother, Dan Hett, confirmed his death on Twitter, saying: "They found my brother last night. We are heartbroken."

Russell Hayward, believed to be Mr Hett's partner, paid tribute to him, saying: "We got the news last night that our wonderful iconic and beautiful Martyn didn't survive. He left this world exactly how he lived, centre of attention.

"I'm in a really bad way so please forgive if I don't reply. Thankfully I have this wonderful family and amazing friends to keep each other strong. I love you Martyn. I always will."

Nell Jones.

A year nine pupil at Holmes Chapel Comprehensive and Sixth Form in Cheshire, died in the Manchester bomb attack, the school said in a statement.

Kelly Brewster

Kelly Brewster, from Sheffield, South Yorkshire, was reported by friends and family to be among those killed in the attack.

Her partner, Ian Winslow, later wrote on Facebook: "Not sure how this works but it isn't good news. Kelly Brewster wasn't one of the unidentified hospital patients. She has sadly passed away in the terror attack yesterday.

"Kelly really was the happiest she has ever been and we had so many things planned together. My daughter Phoebe will be absolutely devastated like we all are."

Megan Hurley

Schoolgirl Megan Hurley is also understood to be among the dead.

The youngster was a former pupil of Halewood Church of England Primary School in Liverpool.

The Liverpool Echo reported that the chair of governors from the school attended a memorial service to the bombing victims at St Nicholas' Church in Halewood on Tuesday, where he said Megan's brother was also "seriously injured".

Angelika and Marcin Klis

Angelika and Marcin Klis are believed to be a Polish couple who died after going to Manchester Arena to collect their daughters from the concert.

Polish Foreign Minister Witold Waszczykowski told a Polish radio station on Tuesday: "The parents came after the concert to collect their daughters and unfortunately we have information that they are dead. The children are safe."

On Tuesday York College student Alex Klis said she was looking for her parents Angelika and Marcin, who had been missing since the attack.

In a post shared on Facebook she wrote: "Anyone who is in any safe place or hospital in Manchester, if anyone comes across my parents please please let me know as they've been missing ever since the attack."

Alison Howe and Lisa Lees

Alison Howe, 45, from Royton, Greater Manchester, was reported missing by relatives along with her friend, Lisa Lees, and are now thought to be among the dead.

A family member wrote on Facebook late on Tuesday: "They took a caring beautiful mum and step mother away from us all she was amazing to us all x love you loads Alison Howe xx"

Chloe Rutherford and Liam Curry

Fears are growing for Chloe Rutherford, 17, and Liam Curry, 19, a couple from South Shields following the attack.

Mr Curry, a former pupil of Gateshead College, is studying for a degree in sport and exercise science at Northumbria University.

Bernard Wills, 36, the cousin of Mr Curry's father, said: "They are a great young couple, really loving, with a bright future ahead and there's nobody that doesn't like them."

Wendy Fawell

Wendy Fawell, a mother from Otley in West Yorkshire, is among those unaccounted for.

Ms Fawell is reported to have gone to the concert with her daughter and friends, and was last seen in the arena's foyer shortly before the blast.

More than 100 people attended a vigil for her on Tuesday night, the Telegraph and Argus said.

Rosemary Thompson, Ms Fawell's godmother told the newspaper she was "sick with worry", saying: "I keep looking out and listening for news and hoping for the best. All we can do is hope and wait."
