Former sub-postmaster Alan Bates says he will consider raising funds for private prosecutions of Post Office bosses over the Horizon IT scandal.
He told the BBC he would act if the authorities did not take cases forward.
"It was fine when the Post Office brought private prosecutions, so if we've got to do it in return so be it", he said.
This will probably drag into the next government the way it's going and it will be interesting to see what PM Starmer does about this when he's in office.
