Second reading support is firm but submissions reveal wider range of opinion and doubts at speed of change.
After months of emotional submissions and some bitter protest, a bill to legalise same-sex marriage appears likely to pass another hurdle with barely a dent in its political support.

With the second reading of the bill likely to be debated this evening, a straw poll of those MPs found only who said he would no longer vote for it.
