Jesy Nelson confronts Wes Streeting over SMA screening delays
Jesy Nelson, the former Little Mix star, has publicly challenged former health secretary Wes Streeting over the slow rollout of spinal muscular atrophy (SMA) screening in the UK. The emotional encounter — which will be broadcast in her new Prime Video documentary Jesy Nelson: Life Changing, released July 17, 2026 — has reignited debate about newborn screening policy.
In the documentary, Nelson interviews Streeting for ITV’s This Morning, asking why the test has not been added to the standard heel prick test for newborns. “Why now? Why did it take for me to come along with a platform for people to take it seriously?” she said, fighting back tears.
Streeting responded by acknowledging that his inbox has been “full of people asking the same questions,” and praised Nelson’s advocacy, adding that many families have been “so thankful” for her work. However, Nelson later revealed she felt “gutted” that she had not pressed all of her points during the interview and asked for two more minutes to speak with Streeting.
The heel prick test gap
Nelson’s twin daughters, Ocean Jade and Story Monroe, were diagnosed with SMA type 1 in 2025 after birth. She has shared how, in just two months, the twins stopped kicking their legs — a sign of the muscle weakness caused by the condition. Early diagnosis through the simple heel prick test, she argued, could have changed their trajectory.
“If it was caught from birth … it’s literally a heel prick test, it is so life changing,” she said in the documentary. “It will never make sense to me that there are people in this world that have a decision over whether my baby will be disabled or not.”
Streeting, visibly affected, said he felt “pressure” to get the testing up and running so that “every child benefits.”
Why the SMA screening row matters now
SMA is a rare but devastating genetic disorder that causes progressive muscle weakness and, in its most severe forms, can be fatal. The UK currently does not include SMA in its newborn blood spot screening, despite the availability of three treatment options that can dramatically alter outcomes if given early.
Nelson’s campaign has thrust the issue into the national spotlight. Her documentary documents not only the personal toll but also her broader fight to change UK newborn screening laws. The good news is that on Thursday, the Department of Health and Social Care announced a consultation on adding SMA to the routine heel prick test — a move likely influenced by Nelson’s relentless advocacy.
The timing is sensitive because Streeting served as health secretary under Keir Starmer’s government until its collapse this year. Incoming Prime Minister Andy Burnham is now assembling his cabinet, and Streeting — once a Labour leadership rival to Burnham — is being discussed for the role of defense secretary. His future may rest on how his record at Health is viewed, including the SMA screening decision.
Streeting’s political pivot
According to a POLITICO report, Streeting is being tipped to replace Dan Jarvis as defence secretary under Burnham. Jarvis is expected to be removed after just six weeks in the role, following the resignation of John Healey over defence funding disputes.
Streeting has been lobbying for the job, but his lack of foreign-facing experience and the fact that he has never held a defence brief have drawn skepticism from some MPs. The “soft left” of the party has also been pushing against him taking a policy-heavy domestic brief.
For now, however, the public conversation is fixated on his health record — and Nelson’s tearful plea may shape how his legacy is remembered.
Broader implications for screening policy and celebrity advocacy
Nelson’s documentary marks a turning point in how celebrity activism interacts with UK health policy. Pop stars and public figures have increasingly taken on roles as policy advocates, from raising funds to pressing ministers directly. Nelson’s approach is personal: she films her own meetings, shares raw footage, and does not shy away from emotion.
Her question to Streeting — “Why did it take for me to come along with a platform for people to take it seriously?” — echoes a broader criticism of how health systems respond to rare conditions. Without a high-profile champion, families often struggle to be heard.
The SMA campaign also highlights systemic issues: the UK’s newborn screening programme evaluates tests based on a set of criteria (including cost, prevalence, and treatment availability). SMA meets many of these criteria, but bureaucratic inertia has kept it out. Nelson’s work may accelerate change not just for SMA but for other rare diseases awaiting screening approval.
What this changes
If the government now moves forward with SMA screening, it will be a direct result of public pressure fostered by Nelson’s platform. Streeting, whether he stays in health or moves to defence, will be associated with the decision. His pressure comment may signal that the consultation is already underway.
For parents of newborns with SMA, the change could mean diagnosis at birth rather than after irreversible damage. Nelson herself said: “If we can prevent this, it’s life changing to people’s families and their children.”
In a political landscape dominated by leadership changes, funding rows, and international crises, this single-issue campaign has cut through. It also underscores how celebrity advocacy — when driven by personal pain — can move the needle in ways traditional lobbying cannot.
Jesy Nelson: Life Changing is available on Prime Video. The documentary follows her journey from diagnosis to confrontation with the political establishment.
