'Sinn Fein warns McCartney sisters'

The BBC reports that the party's chief negotiator has cationed the sisters of Robert McCartney not to get involved in politics.

One of the McCartney sisters is threatening to challenge Sinn Fein at the polls but Mr McGuinness said they could risk popular support.

"To step over that line, which I think is a very important line, into the world of party politics, can do a huge disservice to their campaign," he said.

"In fact, it can dismay and disillusion an awful lot of people, tens of thousands of people who support them in their just demands."

The BBC also reports that two of the party's candidates and a former party councillor were present the night McCartney was stabbed.
