For the benefit of UK readers of this site (and, incidentally the rest of Europe, imo), I am going to copy a post of mine that I've made elsewhere.
There is a method by which members of the public can petition parliament, with that petition forming the basis for a commons debate. The parliament website says that it will "take the existing threshold of 100,000 signatures for a petition to be considered for debate in the House as a starting-point. But it also noted that there may be occasions when a debate is not appropriate—such as when a debate has already taken place in the House on the same subject"
The petition I have in mind is here:
Petition for a second EU Referendum
It doesn't have quite the rationale I'd have used - personally I'd have gone with something like "Whereas the leave campaign grossly misrepresented their position and flat out lied to the voting public we the undersigned..." but there's no point filing multiple petitions to the same end, as that could potentially split the vote, resulting in a much weaker case for a second referendum.
Of course, parliament has already debated the issue, so the chances of getting a second referendum are slim indeed. But slim is not nil! If enough signatures are gathered, if there is an overwhelming show of support, there is always a chance. What counts as overwhelming? Well, considering about seventeen and a half million people voted to leave the EU, I'd say about twenty million signatures would be required to guarantee a second chance. How can we get that many signatures? One at a time!
Bearing in mind that in the immediate aftermath following the results about £150 billion was wiped off our national worth, one of the leaders of the leave campaign admitted that the campaign (not him, of course, never him) lied about at least one of its major promises, and, listening to Nicola Sturgeon we are facing the breakup of Great Britain itself, we simply cannot sit back and do nothing.
So, if you voted to remain in the EU, I'm sure you need little persuading. Please sign the petition.
If you did not vote, and, like me, are aghast at what has happened, and what will almost inevitably happen, please sign the petition.
If you voted to leave the EU, in all good conscience, and are now realising that you were misled by the leave campaign, and are, similarly, shocked by the reactions and revelations that have followed, please, do the right thing, and sign the petition.
Finally, after you have signed the petition, hang on to some hope, there is still a faint glimmer of it, and share this post, share the shares, or, in any other way you can, make as many people as you can aware of the petition, and encourage them to sign it.
Please, before it's too late!
