'A disastrous outcome for unionism' - @JimAllister reacts to #AE17 results

It has been the biggest shocks to the political landscape in the history of Northern Ireland. For the first time there is no unionist majority at Stormont. Sinn Fein has had its best result ever, coming less than two thousand votes - and just one seat - behind the DUP. And Northern Ireland's founding party, the UUP, have slipped into fourth place, behind both their nationalist rivals. Stephen got reaction from TUV leader Jim Allister.
