This would be associated with the UK House of Commons votes on Brexit at about this time - firstly, whether to pass the Withdrawal Agreement Bill forward for a second reading en route to becoming law and defining the terms of the UK’s Brexit, and secondly to approve the Government’s timetable for the passage of the Bill.
the Bill was passed so on the face of it the majority of MP’s support the Prime Minister’s deal. But the second vote was rejected, so the Bill will take more time to be finalised than is available before the PM’s target Brexit date of 31/10, therefore he will need an extension beyond that date from the EU Council in order to finalise the Brexit terms into UK law. As a result of losing the timetable vote, the Government has put the Bill on hold. The next expected devleopment is a reply from the EU Council to say if there will be ab extension and how long it will be.
If you’re not following this in real time, stay away from EUR- and GBP-based pairs at least until the final Brexit deal and its date are finalised.
