Danske Bank's analysts note that on Thursday, a majority in the House of Commons passed an amendment, making it harder for the UK's government to prorogue Parliament in the run-up to the current Brexit date of 31 October.

• “While this does not prevent a no-deal Brexit outcome (it is still the default option from a legal point of view), it makes it more difficult for Boris Johnson (assuming he wins the leadership contest) to force a no-deal Brexit through by sending Parliament home.
• Some 17 Conservative rebels voted against their own government (which did not include politicians such as Phillip Hammond), supporting our view that it is hard to find a majority for a no-deal Brexit outcome.
• We may soon have a more pro-Brexit prime minister but it does not change the arithmetic in the Commons.”
