James Ashley: Shot at close range

The force was severely criticised by two independent inquiries for the operation which saw suspected drugs dealer James Ashley, 39, shot by police marksman Chris Sherwood at his flat in St Leonards in January 1998.

Sussex Police Authority Chairman, Margaret Johnson, said Deputy Chief Constable Maria Wallis would take over command of the force and a new chief constable would be appointed "as soon as is reasonably practicable".

Ms Johnson said: "We have full confidence in Maria Wallis.

"The decision announced today is a proper reflection of the views held by all members of the authority.

"We wish Mr Whitehouse well in his retirement.

We shall remain focused on crime priorities and taking forward improvements in the force's performance that we are now beginning to see

Mrs Wallis said: "This has been a difficult time for the force.

"But the task for everyone within Sussex police is to stay focused so that we continue to improve and work together in partnership with the community."

"The important message to the workforce and the people of Sussex is that we shall remain focused on crime priorities and taking forward improvements in the force's performance that we are now beginning to see.

"The early signs are encouraging.

"Most of the figures are pointing in the right direction."
