A reference to taking down calendars of naked rugby players, sent in error to schools, has prompted a council to apologise.
Derbyshire County Council sent an email last week about updates on its children's services facilities during lockdown.
It offered advice to staff on using video call software, such as Skype, for contact with young people who are subject to safeguarding protection measures.
The update also said: "Check your background: Make sure there's nothing unsuitable on the wall (like my friend's calendar of naked rugby players - luckily it was a colleague call!)".
Instead of just going to staff, the email also went out to schools.
The council apologised for "any offence".
