The full data have not been made available yet.
But there is a calculator, inserting your postcode and a tool to play with changes of %. Even 1-2% variation can +1 remain seat

However if the aim is truly to defeat the BXP the most economical shift of votes is in fact towards the LDs @ +c.6%
In fact Labour would still get its first seat if it lost 8% of their prospective vote.
They are, in effect, wasted votes and +10% is going to be hard.
Also there is another Remain United poll due out Tuesday that I believe will provide regional analysis and use MRP data, & quite large.
