This is an interesting article.
"The revelation could have major implications for Sinn Fein and the party's anti-crime stance here."
Not only do other parties have links to people who they would rather not, however Sinn Fein are extremely quick to jump on the back of anyone to remind them of anything.
I would be interested to see if die hard Sinn Fein people disassociate themselves completely with this article? The real question is for republicans and ex republicans - why do these people need to remain active?
