Brexit in UK

Hi

In Tuesday parliament possible will vote about Brexit deal negocjated by Teresa May.
Probably in 80% British MP-s Telling what not accepting it.
In my view can be start big political rotation in parliament and government.
For £ mean it drop down.
I’m planning swich on two pending transactions First transaction will be buy stop over £ price, and second transaction on sell stop under £ price.
Transactions I’m planning swich-on 5 to 10 minuets before parliament voting.
But is possible what voting can move in date as well.
But we will see .
