Dr Kasim Ahmed is an NHS doctor, specialising in Geriatric Medicine and General Internal Medicine. He came to public attention as  ‘Faithful Kas’ in series three of The Traitors on BBC One. Following his time on The Traitors, Kasim made a series of media appearances on daytime television, across national and local radio stations, and on social media and quickly became a fan favourite.

Kasim took an unconventional route into medicine, having started a degree in Mathematics at King’s College, London, at the recommendation of his tutors, before transferring into a Biomedical Sciences. During his undergraduate degree, he realised that his passion was working with patients as well as academia, and so he chose to pursue a career in Medicine.

After completing an accelerated medical degree at Imperial College London, he began his career in the East of England. He gained clinical experience in various surgical specialties, medical specialties, psychiatry and community medicine before choosing to specialise as a physician in Geriatric Medicine and General Internal Medicine. He is a member of the Royal College of Physicians.

As a geriatrician, Kasim is keenly aware of medical, social and ethical issues that arise with an aging population, as well as how political turbulence can affect vulnerable populations on both the personal and national level. He practices inpatient, outpatient and community medicine, and is keen to ensure that each patient has the best possible clinical outcomes while respecting their personal, social and religious values.

As well as a practicing clinician, Kasim is also a keen academic and medical educator. He has been involved in training medical students, newly qualified doctors and more senior resident doctors in clinical practice. He is currently completing a master’s degree at UCL in Medical Education, and hopes to use his research to challenge approaches to education in an ever changing health climate.

Kasim has shared his medical expertise with the nation with several appearances on BBC’s Morning Live on television and on the Today programme on radio.

Outside of work, Kasim and his wife, Zahraa, enjoy going on adventures with their daughter, Noura- both real and imaginary! Always keen to try new things, he has previously taken up Kung Fu, ice skating and squash. More recently, he has taken up running as a hobby which helps balance his parenting schedule.

Kasim is keen to use his platform to engage with the public in issues affecting physical and mental health, exploring advances in medical research and technology, and exploring personal stories of those suffering from acute and chronic medical conditions. Additionally, he takes great pride in exploring and understanding how different cultures approach health and wellbeing and bringing the best to his own medical practice.

Dr Marc Abraham OBE, or ‘Marc the Vet’ as he is usually known, is a multi-award-winning veterinary surgeon, broadcaster, author, and animal welfare campaigner; regularly appearing on shows including BBC Breakfast, Sky News and ITV’s Tonight. In 2025, Marc released his film Dogspiracy which follows his travels to the US to explore the controversies surrounding the trade and sale of puppies in American pet stores. He explored the same topic in 2015 as a producer on the US documentary, Dog by Dog. Marc has experience across a range of different veterinary work and volunteers abroad, bringing a unique perspective to both broadcast and corporate work.

Marc is the author of four books for adults: Vet on Call, Pets in Need, Lucy’s Law: The Story of a Little Dog Who Changed the World, and most recently #BeMoreMosquito: How you can campaign and create change. In 2026, Marc released his first book for children, Leon’s Reef. The picture book aims to teach children that working together to look after ourselves and our environment makes life better.

Marc writes blogs and articles to raise awareness for animal welfare across local, national, and international media, is the resident vet on BBC Sussex and BBC Surrey and shares tips on his popular X and Facebook accounts. Marc has successfully collaborated with a whole host of household brands and events and is often invited to speak at public engagements as well as at meetings in Parliament.

His passion for animal welfare has also seen Marc volunteer overseas for numerous animal welfare organisations. These include vaccinating dogs against rabies in the Mumbai Slums, rescuing dancing bears in Ukraine, saving cats and dogs in post-tsunami Thailand, rescuing dogs from dogmeat farms in South Korea, neutering pets deep in the Amazon Jungle, working with pit-bulls in US prisons, operating on street dogs in Udaipur, India, going undercover to investigate Finnish fur farms, rescuing ex-breeding dogs and puppies from U.S puppy mills, as well as performing dental work on a rescued Moonbear in Chengdu, China.

Marc campaigns extensively for animal welfare issues both in the UK and US, including promoting rescue pet adoption and responsible dog and cat breeding. In 2009 he set up Pup Aid, a national puppy farming awareness campaign, featuring an annual celebrity-judged dog show in London’s Primrose Hill. Responsible for three of the biggest pet welfare government e-petitions of all time, Marc is also the co-founder and secretariat of the All-party Parliamentary Dog Advisory Welfare Group (APDAWG) and helped source rescue dog Dilyn for Boris Johnson and his wife Carrie.

After leading a 10-year campaign, including 300+ visits to Westminster to lobby MPs and Ministers, the Government passed Lucy’s Law, banning the commercial third-party trade in puppies and kittens. This made all dog and cat breeders accountable by providing a legislative framework to help investigation and prosecution, in turn providing support and transparency for prospective pet owners. The campaign was also successful in changing the law in Wales, Scotland, and later in Northern Ireland.

Based in Brighton, Marc currently works at The Mewes Vets in nearby Rottingdean and regularly visits local primary and secondary schools to talk with pupils about caring for animals and looking out for one another. He is the proud ambassador for, and patron of, several animal charities including All Dogs Matter, Edinburgh Dog and Cat Home, Humane Society International UK, SPANA, Oldies Club, Friends of Animals Wales, Nowzad Dogs, Compassion in World Farming, and Together Co.

In recognition of his work at home and worldwide, Marc was awarded an OBE for Services to Animal Welfare by King Charles III at Windsor Castle, after being announced in the 2021 Queen’s Birthday Honours List.

During her operational tour of Bosnia in 1997 as part of NATO’s Stabilisation Force (SFOR), Saleyha was inspired to re-train as a doctor, after witnessing severe trauma suffered by Bosnian civilians caused by landmines.
