     Removed the document 'Steve Holborow, Senior Responsible Owner for the Falcon Progamme' since the entry is below the £100m threshold for a Departmental Major Project and instead falls under the "Other Major Project" (OMP) categorisation, it will no longer require an SRO letter. Therefore, removing the SRO letter from GOV.UK is aligned to this approach. The [new guidance](https://intranet.cabinetoffice.gov.uk/about-the-cabinet-office/our-purpose-priorities-and-performance/cabinet_office_strategy_directorate_1/cabinet-office-strategy-unit/co-project-delivery-hub/assurance-for-cabinet-office-major-projects/ ) as to the sizing of projects.

Details

Each government department publishes the letters of appointment for their GMPP Senior Responsible Owners (SROs). These letters include the date of appointment, the project deliverables, what the SRO is responsible for and how long the role is expected to last.

The guidance for officials giving evidence to Parliamentary Select Committees, known as the Osmotherly Rules was updated on 17 October 2014. As part of this update we are committed to publishing GMPP SRO letters of appointment.
