The former leader of Chichester District Council clashed with the new leader during the first cabinet meeting held on Tuesday.
Cllr Eileen Lintill was forced to defend her choices for a panel for the development plan and infrastructure.
Cllr Tony Dignum who stepped down as leader after the elections in May, described the make-up of the panel as ‘odd’ due to the political balance.
The panel does not have to reflect the political make-up of the council but Cllr Dignum, a Conservative councillor, said: “I was very surprised to see that the development plan and infrastructure panel has only four members from the Conservative group and six from the various minorities, including four from the Liberal Democrats, the same as the number from the Conservative group, which does seem very odd indeed.”
The ten councillors in the panel advise the cabinet on issues such as neighbourhood plans and the Local Plan.
Cllr Lintill, also Conservative, responded: “I don’t think it would be right to fill it with cabinet members.
“I don’t think it would be right to fill it with people from the national park and that is why we have made our decision.”
The cabinet went on to vote in favour of the suggested membership for all the panels, however, Cllr Dignum asked for his opposition to be recorded.
