LONDON (Reuters) - Most members of a pro-Brexit faction of UK Conservative lawmakers are likely to back a proposal for the so-called Irish backstop to be replaced with other arrangements to avoid a hard border in Ireland, one member, who declined to be named, said.

May has asked her Conservatives lawmakers to support the proposal, or amendment, when parliament votes on it on Tuesday evening, to show the European Union there is popular support in parliament for her attempt to renegotiate the deal.
