Johnson pushes for Brexit deal vote

By AAP Newswire

British Prime Minister Boris Johnson will try to put his Brexit deal to a vote in parliament on Monday after he was forced by his opponents to send a letter seeking a delay from the European Union.

With just 10 days left until the United Kingdom is due to leave the EU on October 31, the divorce is again in disarray as Britain's political class argue over whether to leave with a deal, exit without a deal or hold another referendum.

Johnson was ambushed by opponents in parliament on Saturday who demanded a change to the sequencing of the ratification of the deal, exposing the prime minister to a law which demanded he request a delay until January 31.

In a twist that illustrates the extent to which Brexit has strained the norms of British statecraft, Johnson sent the note to the EU unsigned - and added another signed letter arguing against what he cast as a deeply corrosive delay.

"A further extension would damage the interests of the UK and our EU partners, and the relationship between us," Johnson said his own letter, signed "Boris Johnson".

The British government insisted on Sunday the country will leave the EU on October 31, and plans to put the deal to a vote in parliament later on Monday though it is unclear if the House of Commons speaker will allow such a vote.

The government has proposed a debate on the deal, according to the House of Commons order paper which says the speaker will make a statement on the proceedings shortly after parliament opens at 2.30pm London time.

The EU, which has grappled with the tortuous Brexit crisis since Britons voted 52 to 48 per cent to leave in a 2016 referendum, was clearly bewildered by the contradictory signals from London.

It was unlikely that the EU's 27 remaining member states would refuse Britain's request to delay once again its departure, given the impact on all parties of a no-deal Brexit.

Sterling, which has rallied more than 6 per cent since October 10, slid from five-month highs on Monday. It hit as low as $US1.2850 in Asian trading before settling around $US1.2920 in London, down 0.5 per cent on the day.

Goldman Sachs raised the probability of the United Kingdom leaving with a ratified deal to 70 per cent from 65 per cent, cut its view of the chances of a 'no-deal' Brexit to 5 per cent from 10 per cent and left its view on no Brexit at all unchanged at 25 per cent.
