Ms Jenner, key solutions manager for GE Capital Solutions, has served as chairman since being first elected in 2006.

She said: 'My job means that I am handling an extremely wide range of issues at the coalface of fleet management every minute of every day. Therefore, I am very conscious of the problems faced by operators in charge of small, medium and large fleets.

'One of the key issues we face over the coming months is to establish a constructive dialogue with the coalition Government on fleet-related matters.

'Historically ACFO has enjoyed a close relationship with a number of ministers in Whitehall departments. We continue to work closely with civil servants in those departments – particularly the Department for Transport, HM Treasury and HM Revenue & Customs – and provide feedback from the ACFO membership on a number of fleet-related topics.

'Now that Coalition Government ministers are in place we are seeking talks with them to ensure they have a thorough understanding of the UK fleet industry and the impact their decisions have on both vehicle operations and company car and van drivers.'

Meanwhile, ACFO director Liz Hollands has resigned from the board for personal and business reasons.

Ms Hollands, a board member for four years, had previously held the posts of chairman and secretary within ACFO's southern region.

Ms Jenner commented: 'The board would like to thank Liz for her many years of distinguished service on behalf of ACFO in a number of roles. Her fleet knowledge, experience and skills will be sorely missed.'
