Senior figures from the Netherlands ‘ two-party ruling coalition held tense talks Wednesday, a day after three Labor Party senators unexpectedly voted down health care legislation and dented confidence in the 2-year-old Cabinet’s ability to cooperate on budget-cutting reforms. Prime Minister Mark Rutte of the free-market Liberal Party and Diederik Samsom of the center-left Labor Party failed to patch together a compromise in talks that dragged into the early hours of the morning.
