The presentation, which also appeared on Portuguese television, featured images of scantily clad women and the chief, Euclides Santos, finished by wishing the 15,000 recipients success in the bedroom.

“Enough with insincere and useless words. What I wish you from the bottom of my heart, is that you have incredible sexual relations, live a merry and happy life, work hard and get well paid,” the slide said.

Mr Santos’ desperately attempted to alert staff to the ‘error in the attachment’, but his actions came too late to save himself from suspension.

Local press said mayor Joao Barbosa de Melo believes the police chief should lose his job, as it was sent during work hours from his work email.

A statement from Coimbra municipality read: ‘After receiving a message containing content inconsistent with the prestige of this town hall in the municipal email box, an address to which all municipal employees have access to, the mayor has decided to initiate disciplinary proceedings.’

The message certainly stands in contrast to that from the UK’s Association of Chief Police Officers this year, which focused on the ‘greatest public order challenges in the history of British policing’, the riots in August.
