It's 40 out of 50 seats declared. I assume they'll each pick up a lot more seats as the results come in.
They have picked up some more - the SDLP are looking bad, it's kinda their own fault, former SDLP leader John Hume , a Sacred Cow of Irish politics, insisted that a peace settlement must involve the IRA, such an equivocating position cost his party electorally in the long run, voters always turned to the SDLP as an exclusively democratic alternetive to the IRA.
