The Southeast and Gatwick Diamond Growth Gateway APPG will launch an integrated transport policy investigation in summer 2026 to examine how regional connectivity can support economic growth and employment.
The cross-party parliamentary group will formally begin the investigation at a House of Commons event to be held in June. The initiative forms part of the APPG’s 2026–27 work programme following its launch in February 2026.
The investigation will assess transport systems across the Southeast and Gatwick Diamond region, focusing on their role in supporting business activity, job creation, and economic regeneration. It will consider issues including rail performance, road congestion, rural mobility, and coordination between transport authorities.
Natasha Irons, Co-Chair of the APPG and Labour MP for Croydon East, said: “People across the region know how frustrating it can be when journeys don’t work as they should, and that has a real knock-on effect for jobs and businesses. This investigation is about getting everyone in the same room and working out what actually needs fixing.”
The programme will include two evidence hearings comprising five themed sessions covering rail connectivity, roads and freight, bus networks, transport innovation, and access to London Gatwick Airport. A site visit and a final report to Parliament will follow, setting out recommendations for government and industry.
The APPG states that the Southeast is home to major employment clusters and the UK’s second-largest airport, but ongoing transport constraints continue to affect productivity and investment. The investigation will examine how infrastructure upgrades and integrated planning could address these challenges.
Mims Davies, Co-Chair of the APPG and Conservative MP for East Grinstead and Uckfield, said: “This is about making sure the region’s transport actually works for the people who rely on it every day, whether that’s getting to work, running a business, or travelling further afield.”
The findings of the investigation are expected to inform future policy discussions on infrastructure investment and regional growth, with the final report due to be presented in Parliament following the completion of evidence sessions and stakeholder engagement.
