What now for Sinn Fein's Brexit demands after European Parliament reject party's position?

What now for Sinn Fein's Brexit demands after the European Parliament overwhelmingly rejected the party's position? Their group's attempt to secure NI's place in the single market and customs union was defeated 374 votes to 66.

Stephen spoke to SF MEP Martina Anderson and TUV leader Jim Allister.
