~~The British government has formally called for Sinn Fein, the IRA's political wing, to be expelled from the multiparty peace talks on northern Ireland.~~ ~~The move had been widely expected after northern Ireland police said they believe the IRA was behind two killings in Belfast last week.~~ ~~Sinn Fein chairman Mitchell McLaughlin says the party will challenge the move by legal means if they have to.~~ ~~We 're going to fight it.~~ ~~And uh we 've already challenged , very strongly, the uh the terms in which this has been presented.~~ But we 're challenging it on the ground that uh the RUC uh have offered an opinion, and this opinion is going to be used as a mechanism for ejecting us from the talks, and uh that's a very serious. ~~Any decision to expel Sinn Fein must be agreed jointly by the governments of both Britain and the Irish Republic.~~
