IT was great to hear that the Court of Appeal has ruled that UK's continued arms sales to Saudi Arabia for use in Yemen's brutal war are unlawful.

The Campaign Against the Arms Trade argued that UK fighter jets and bombs are being used to kill civilians and violate international law. The Court of Appeal concluded that it was “irrational and therefore unlawful” for the international trade secretary to have licensed weapons exports without assessing whether past incidents broke international law and if there was a “clear risk” of future breaches.

Judges found that although the UK had "engaged closely" with Riyadh in attempt to minimise civilian casualties in Yemen, that fell short of the legal obligation to assess the risk of war crimes.

No matter what atrocities it has inflicted, the Saudi regime has been able to count on the uncritical political and military support of the UK.

The bombing has created the worst humanitarian crisis in the world and thousands of people have been killed in Saudi-led bombing. Many more have died as a result of an ongoing humanitarian catastrophe including a cholera outbreak and starvation.

UK arms companies have profited every step of the way and must immediately follow the lead of the likes of Germany, the Netherlands and Finland in immediately ceasing arms sales to Saudi Arabia.

The man who was the Foreign Secretary in the period considered by the judgement, who signed off the export licences and should therefore be held responsible, was none other than Tory leadership frontrunner, Boris Johnson.

Scotland's sinkhole fear

THE land contamination issue potentially affecting St Ambrose and Buchanan High schools in Coatbridge ("Issue of the week: Health fears over ‘toxic waste’", The Herald, June 15) will unfortunately be the first of many such cases.

Indeed, we have also seen similar issues raised with the new development at Polmadie (the former White’s Chemical Works). And today, no housing developments have an Environmental Impact Assessment (EIA).

The common theme is the Scottish Government's watering down of the EU EIA regulations in 2014 and 2017. So now developers (or councils) can save a few bob by building on dodgy sites (with flood, contamination, ground or landfill, or habitat issues) without rigorous scrutiny. The question is not if, but when, Scotland gets its first sinkhole.

Time to unplug the amps

HIGHLIGHT of the recent John Barrowman performance at the Glasgow Royal Concert Hall (June 18) was the appearance of John’s 84-year-old mother, who was given a standing ovation when she sang The Wedding.

Is it just me or is the deafening amplification at such concerts the norm? My friend and I sat there wishing, just for one number, they would unplug the amplifiers and let us hear John’s splendid voice and his excellent band with the minimum of help from their sound engineer.

Natural sound: what happened to it?

Initial thoughts

WHILST leaving myself open, after the surrendering of a 3-0 lead, to accusations of sour “grapery" ("Crying game as Scotland pay the penalty", The Herald, June 20), I think that with some justification, last night's shenanigans spoke some truth to power in revealing the true meaning of the abbreviation VAR – Very Average Refereeing.
