Freedom of Information requests have revealed that Bristol City Council has paid off more than 120 staff with ‘gagging orders’.
The clauses – which are usually part of a severance payment - prevent staff from speaking out about their former employer after they no longer work there.
Charlotte Leslie, MP for Bristol North West, has said the practice must end as it is preventing former employees with legitimate complaints about the council to speak out.
According to reports, one former boss of the Serious Fraud Office received £462,000 and signed a confidentiality agreement.
In a survey of 256 councils in Britain, the figure for Bristol is the second highest in the country.
