Brexit 2nd Referendum Poll 52-48 for Remain

Polling for a 2nd Brexit Referendum show 52% to 48% in favour of Remain..

If you believe in Polling results then you may feel that Remain will win, just as people did in 2016 with the Referendum that had polling showing a 52% Remain win.

However, the actual result was not the same as the polling.

• In June 2016 just before the referendum, the Polls showed 52% to 48% in favour of Remain, and LEAVE won.
• In Sept 2018, the Polls again showed 52% to 48% in favour of Remain; would LEAVE win again?

The poll results are the same now as they were just before the referendum

Does this mean that Remain would win a second Brexit referendum?

Does this mean that Leave would still win another Referendum.
Would any government want to pay for another referendum that might be exactly the same?
