But Grandad you are making the assumption that Labour's idea of a second referendum is what people want - "to review their Brexit vote". You make it sound like a good thing.
Labour wants a second referendum. Many people find the idea repugnant and insulting.
Back in 2017 this article appeared in the Independent.

"I voted Leave to call the establishment’s bluff. To test that we are, indeed, a free and democratic country. To confirm that I was able to say no to the European Union. After all, as Salman Rushdie once wrote, the freedom to reject is the only freedom."
"We know that the majority of Brexiteers voted to retain and reinstate the UK as a sovereign state, whether it be for control over our laws or our borders. In fact most of the reasons why people voted to Leave, as cited in the the Lord Ashcroft polls at the time, were summarised in points that contained words like “decisions”, “control” and “choice”. People voted for the freedom to have the ability to say no."
"Despite this, the British people’s decision to put the EU behind us and to take responsibility for the future of our country is met by continuing doubt and harassment from those urging for a second referendum. Even the utterance of a second referendum insults the very concept of our precious democratic system, and its undermining should outrage us all. It is an open attack on our individual freedoms – to say no, and have the establishment take us seriously,"
This article was written two years ago when Remainers were demanding a second referendum. They still are. Two years ago and Remain MPs and the Labour Party are still telling us this is what should happen. Back then she wrote
The truth is, if certain MPs can’t have it their way and remain, they will attempt to make Brexit a messy conflict for the rest of us – and that is something we must not abide.
And it has happened.
It ends The dismemberment of democracy, triggered by the picking and choosing of election results, starts a dangerous precedent that will permit your own demise if your desires fall foul of the EU’s plans. You are endorsing, without sounding too dramatic, the dismantling of the very basis of our Western civilisation
Your decision lies before you: it is either democracy, the power of the people, or technocracy, control by a few.
