Brexit backstop: What are the 'alternative arrangements'?

Theresa May is seeking further talks with EU leaders over the Brexit withdrawal agreement. MPs voted for an amendment that calls on the government to pursue "alternative arrangements" to replace the Northern Ireland backstop. The Brexit Secretary, Stephen Barclay, said there were a number of options. "There are issues in terms of having time limits, issues in terms of exit clauses, issues in terms of technology and this will be the nature of the negotiation with the EU in the coming days," he said. The EU says, however, it does not want to renegotiate or reopen the withdrawal agreement.
