From the video:
At 1:37, she says:
“… it’s about time for the opposition to offer us, the people, the opportunity to vote against Brexit.”
I wonder what she thought the Brexit referendum of 2016 was for? The last time I looked, I lived in a democracy. Before the vote, we were told that whatever the result was, it would be implemented. The choice was binary – leave or stay in the EU. The majority voted leave. It doesn’t matter whether 99% voted leave or 50.001% voted leave. If the majority voted to leave, we leave. That was the deal. We were also told that this vote to either leave the EU or stay in was a “once-in-a-lifetime decision”:

Earlier, in 2013, the then PM (David Cameron) said, "It is time for the British people to have their say. It is time to settle this European question in British politics. I say to the British people: this will be your decision." [https://www.bbc.co.uk/news/uk-politics-21148282]
The notion that prior to the vote, the result of it would be implemented, was absolutely accepted by both ‘remain’ and ‘leave’. I don’t recall – nor can I find – any evidence that either side had any reservations about the implementation of the then unknown result. Of course, at the time, it was widely believed (as I did) that the British public would vote to ‘remain’.
If there is to be another vote on whether to rejoin the EU, that should be no sooner than the year 2041. Why? Because “once in a lifetime” (or to put it another way - once in a generation) means around 25 years which generally averages the time from the birth of a parent to the birth of a child.
So I would say to the lady in the video: no. We're not having another vote on Brexit anytime soon. To do so would be an appalling betrayal of the British people and it would seriously undermine our democracy. For better or for worse, we're out of the EU.
