Former Polish government officials may face charges following an investigation into their use of the notorious Pegasus spy program to monitor political opponents and others.

Poland officially launched a parliamentary inquiry into the former government's potential misuse of the commercial surveillance software in February.

On Monday, Attorney General Adam Bodnar told The Guardian that Pegasus victims would soon be told they had been targeted by the NSO group's controversial snoopware.

"There's a decent chance that within a couple of months we'll have pretty extensive knowledge of how this equipment was used and for what purpose," Bodnar said.
