Theresa May has vowed to resign if her twice rejected deal is approved. The announcement came as MPs held backbench-led "indicative votes" on eight different Brexit options - none of which secured a majority.
The options included - no deal, a customs union, Norway style deal and a second referendum.
While some senior Brexiteers have moved to support her deal, May must still try to gain the backing of the DUP to get the deal passed, but they refuse to support her.
