Cabinet Secretary’s Outstanding Leader Award Shortlist

Lewis Attenborough

Department for Work and Pensions

Lewis took up a senior leadership role at the start of 2024 during a period of high workload, low morale and elevated staff turnover. He was tasked with stabilising delivery, rebuilding trust and restoring performance across multiple business areas.

Lewis led a values-driven, co-designed recovery plan focused on engagement, inclusion and wellbeing. Key interventions included extensive engagement sessions with frontline and back-office staff, the introduction of People-First frameworks, the creation of cross-grade working groups to give junior staff influence over local priorities, and 1:1 leadership mentoring to strengthen line managers. He emphasised visible, transparent communication and weekly check-ins to track progress.

The impact was measurable and sustained: staff engagement scores rose by 28%, absenteeism fell by 35%, and service performance exceeded all quarterly targets for the first time in 18 months. Over 80% of colleagues cited Lewis’s leadership as a key reason for remaining in post. His approach also generated a renewed sense of belonging and purpose across teams.

Lewis now regularly mentors aspiring leaders, advises on cross-departmental culture initiatives and represents operational delivery at directorate level. His methods — combining staff empowerment, clear governance and focused wellbeing interventions — have delivered rapid performance recovery and a scalable blueprint for resilient, people-centred leadership.

Nicola Hughes

HM Courts & Tribunals Service

Nikki is a transformative leader within HMCTS and has delivered measurable impact across complaints across National Services, by centralising complaint handling. She led the successful merger of legacy and Service Centres complaints teams, creating a collaborative and psychologically safe environment that empowered staff to co-design processes and adopt best practices. Initially Nikki was operating two grades higher than her substantive role and was able to secure promotion due to her exceptional work.

Under her leadership, the probate complaints backlog of over 600 cases was reduced to under 50 cases one month ahead of schedule. She reallocated resources, secured additional staff, and delivered targeted training, ensuring high service standards were maintained throughout. Following this, Nikki piloted the centralisation of civil complaints, managing over 650 cases monthly. Response rates improved from 43% to 93%, while escalations dropped from 48% to 14%, reflecting both operational efficiency and enhanced team performance.

Her leadership and operational excellence were recognised nationally when she won Complaints Manager of the Year at the UK National Contact Centre Awards, HMCTS’s first-ever gold award in the programme. This is a national prestigious award, in which Nikki competed against quality leaders across public and private sector organisations.

Nikki combines integrity, empathy, and a people-first approach to inspire teams, deliver measurable outcomes, and improve service delivery. Her work has reshaped national complaints handling, driven lasting efficiency improvements, and established a model of high-performing, inclusive leadership that continues to influence colleagues across HMCTS and the wider Civil Service.
