Are Sinn Fein guilty of double standards over cuts north and south of the border?

It's one of the most common criticisms of Sinn Fein - that it has double standards over Government cutbacks north and south of the border. Opponents say the party condemns cuts in the Republic, while helping implement them up here in the Stormont Executive. Sinn Fein deny the claims. One of its MLAs Phil Flanagan has now hit back at the party's critics in an article for the online Irish newspaper, The Journal.
