RE: Vote on Saturday and LLoyds19 Oct 2019 16:20
MPs have backed an amendment - the 'Letwin amendment' - that withholds support for his agreement until all the legislation that's needed to be passed is in place.
It also means the prime minister will have to write a letter to Brussels tonight to ask for an extension to the Brexit deadline.
It passed with 322 votes to 306, after the DUP opted to back the amendment.
The amendment was put forward by Tory MP Oliver Letwin.
Mr Letwin said he supports the deal - but was putting forward the amendment to ensure the parliament will be "secure" knowing that an extension has been requested, no matter which way subsequent votes on the deal go.
