Muggle Liaison Office

"Less than a year later a harassed-looking Fudge had appeared out of thin air in the cabinet room to inform the Prime Minister that there had been a spot of bother at the Kwidditch (or that was what it had sounded like) World Cup and that several Muggles had been "involved", but that the Prime Minister was not to worry, the fact that You-Know-Who's Mark had been seen again meant nothing; Fudge was sure it was an isolated incident, and the Muggle Liaison Office was dealing with all memory modifications as they spoke."

- Description

The Muggle Liaison Office was a division of the Department of Magical Accidents and Catastrophes presumably responsible for wizard-Muggle relations. Given the lack of Muggle awareness of the wizarding world, in accordance with the International Statute of Wizarding Secrecy of 1692, it can be presumed that the Muggle Liaison Office fulfilled its duties in a very one-sided manner. Those who worked in Muggle Relations presumably worked with this office.

History
Celestina Warbeck's father was a "minor functionary" in the Muggle Liaison Office in around the 1910s.

In the summer of 1994, after the Death Eater incident at Roberts's campsite, the Muggle Liaison was tasked with memory modifications.
