Bernadette Kelly has been appointed as the new permanent secretary at the Department for Transport (DfT).
Ms Kelly has been at the DfT for nearly two years as director general of its Rail Executive.
She was previously director general for business and local growth at what was then the Department for Business, Innovation and Skills.
She said: ‘I am delighted to be appointed as permanent secretary at the Department for Transport.
'DfT is a great Department and I have hugely enjoyed working here in rail. It is an honour to be asked to lead the department and I’m looking forward to the challenge ahead.’
The appointment follows previous permanent secretary Philip Rutnam’s recent move to the Home Office, which was announced in February.
It was made by the cabinet secretary with the approval of the prime minister and the transport secretary, Chris Grayling.
Mr Grayling said: I’m very pleased that Bernadette will be the new permanent secretary at the Department for Transport. Her knowledge and experience of the department mean she is very well placed to make an excellent start in her new role and I look forward to continuing to work with her.’
