Nigel Vooght has stepped down both as a politician and chair of the senior Policy and Finance Committee. He claims his relationship with the president of the States of Alderney has broken down 'irreparably.'
Nigel Vooght left office over the weekend (14,15 December).
His resignation letter blames political infighting between States members and a broken relationship with William Tate, the president of the States of Alderney, who he accuses of political interference.
Mr Vooght was elected as a States member two years ago and became chair of Alderney's senior committee, Policy and Finance.
He says his work there was hindered by 'a few' politicians who 'are so divided and consistently attempt to belittle others who are trying their hardest.'
His resignation letter says Alderney has much potential but it faces great external challenges and these must be the focus of the States.
Mr Vooght says his attempts to bring about change were 'being blocked at every turn.'
He implies that neither he, nor the new chief executive, Theo Leijser, received adequate support over recent weeks from States president William Tate, who he alleges blocked items getting onto the States agenda.
A by-election will take place in the New Year to replace Mr Vooght.
Guernsey's President of Policy & Resources, Deputy Lyndon Trott, says he was disappointed to hear about My Vooght’s resignation.
"In all my dealings with him I found Nigel to a very capable person who was trying to do his best for the people of Alderney.
He took a responsible and pragmatic approach to Alderney’s relationship with Guernsey, engaging firmly but fairly.
I wish him well and thank him for his constructive approach to working with Guernsey on what are often challenging issues."
