In a statement, Mr Brown criticised Hope Not Hate as “state backed liars” and said he had since moved on from Patriotic Alternative.
He is now a member of the Homeland Party, a group founded by former British National Party activist Kenny Smith.
The Courier previously reported how Mr Brown had been suspended by the Royal Mail after his links to the white-nationalist group Patriotic Alternative were reported alongside historic remarks posted online.
A spokesman said: “We have been made aware of the reporting and are currently carrying out our own investigation.
“It would not be appropriate to comment on the details of any individual case, however we do suspend employees when serious allegations are made in order to protect colleagues and customers.”
