Alert readers may have spotted that the “Vote No Borders” cinema advert featured on this much-viewed Wings article from a few days ago can no longer be played from the campaign group’s YouTube page, returning a “Private” error.

An even more alert reader, however, had already made a copy.

And while the entire series of ads has now been effectively banned by all of Scotland’s cinema chains, all the other ones are still present on the website while the NHS one (described as “a light-hearted sketch”) has vanished. And now we’ve found out why.

The above is an email sent to a Wings Over Scotland reader from Great Ormond Street Hospital for Children, probably the UK’s – if not the world’s – most famous such institution. As the transcript linked above shows, GOSH was cited in the VNB ads with the suggestion that it would become “out of bounds” to Scottish children (or as the ad put it, “foreigners”) should Scotland vote for independence.

The reality seems to speak for itself.

We don’t think we’re yet anywhere near the lowest depths the various factions of the No campaign will sink to between now and September, but it seems determined to drag bystanders down into the sewers with it in its at-all-costs defence of the Union.

We’ve already seen Scottish Labour’s Anas Sarwar grossly misrepresenting the views of esteemed anti-poverty campaigners the Joseph Rowntree Trust – something for which Sarwar never publicly apologised, nor corrected his falsehood – not long after his party did much the same to the Economic and Social Research Council.

And of course this week we’ve had not one but two highly respected institutions complain that the UK government was utterly distorting and exaggerating their findings on the cost of setting up an independent Scotland’s infrastructure.

We obviously can’t predict who the next innocent casualties of the No campaign’s indiscriminate lie-bombing will be. All we can say with any degree of confidence is that the good people of Great Ormond Street Hospital won’t be the last.
