This included: Three online sessions were held (23rd September, 28th October 2025 and 21st January 2026).

This included: Three online sessions were held (23rd September, 28th October 2025 and 21st January 2026). We carried out market engagement to test capability, gather feedback, and inform the procurement approach.",
