Prime Minister Keir Starmer has chosen to keep Mike Tapp in his role as Home Office Parliamentary Under-Secretary of State, even though Home Secretary Shabana Mahmood formally asked him to remove Tapp for breaching the ministerial code.

Tapp, appointed to the position on 6 September 2025, published an article he had not cleared with his superiors. In it, he argued that migrant care workers should not face long waits to apply for permanent settlement — a position that contradicted the government's official immigration stance. Mahmood, who oversees immigration policy in her department, escalated the matter directly to Starmer, requesting Tapp's dismissal. Starmer's office confirmed Tapp remains in post.

The ministerial code is a written rulebook for government behaviour. It requires ministers to get approval from their Secretary of State — and sometimes from the Prime Minister's office — before making public statements on live policy matters. Publishing without that clearance is a clear breach, and Mahmood's decision to bypass internal channels and go straight to Starmer shows she took it seriously.

That Starmer declined to act is the more significant development. Disagreements between a Secretary of State and a junior minister are routine. A Prime Minister publicly overruling a Secretary of State is not. Mahmood's authority over her department's messaging has now been questioned in public, and her junior ministers know they can appeal to Starmer if she tries to discipline them. Starmer's choice might reflect genuine support for Tapp, a shift in how the government wants to talk about immigration, or simply a calculation that firing him would create worse headlines than keeping him. The practical effect on how the Home Office operates is the same either way.

The underlying issue Tapp raised — how long migrant care workers should wait for permanent settlement — sits at a genuine tension within government immigration strategy. The care sector depends heavily on workers from overseas, and the Home Office's own data shows the stakes of that reliance. Between July 2024 and June 2025, employers lost 1,948 visa sponsor licences for rule-breaking — double the previous year's rate. Tighter enforcement of those sponsorship rules and longer settlement waiting periods pull in opposite directions for workers already employed in British care settings. Tapp's article, whether authorized or not, laid that contradiction bare.

This context shapes how to read what happened. Mahmood has built a public identity around strict immigration compliance. Tapp's statement muddied that message not just procedurally but substantively — by suggesting the government should consider the welfare of migrant care workers at a moment when it is emphasizing enforcement. That Starmer kept him in place suggests the Prime Minister is not willing to let enforcement messaging drown out other considerations, or at least that he will not grant Mahmood a blank check on how these difficult trade-offs get communicated to the public.

What unfolds inside the Home Office from here merits close attention. Mahmood has put her objection on the record publicly, so Starmer's refusal to comply carries real cost to her standing. Junior ministers who survive a code breach usually do so because the Prime Minister judges that sacking them would hurt politically more than keeping them. They rarely survive a second breach. Tapp now operates in a department where his Secretary of State has formally documented her disagreement with him. That is not a comfortable arrangement for either of them, and such tension rarely stays frozen.
