Keir Starmer jumped on a jet last week and headed to Brazil. A 12,000-mile round trip to a climate summit where he re-committed the UK to Carbon reduction targets that will further impoverish people in the UK - without making a blind bit of difference to global temperatures - and either collapse or relocate abroad our once world-leading manufacturing industries.

Starmer's obsession with net zero is putting a giant, self-inflicted nail in the coffin of UK PLC. Decarbonisation ultimately means deindustrialisation and dependency on China, and while other countries are finally waking up to that fact and turning their backs on this pseudo science, Starmer is digging in, even introducing climate change into the school curriculum to brainwash the next generation to his way of thinking, yet another disgraceful, socialist act of self-harm on this country.

There was absolutely no need for Starmer to go to COP30 in South America (other than to satisfy his endless self-important desire to strut around on the world stage). In fact, he'd have been well advised to stay away, but so desperate was he to duck out of Wednesday's PMQs - to avoid any questions on the growing problems of his making at home on immigration, prison escapees, rising unemployment and ministerial sleaze - that he fled the country to look important elsewhere because he doesn't back home.

In contrast, Presidents Xi, Trump, Putin and Prime Minister Modi - the leaders of the four biggest carbon-emitting countries - didn't attend.

Laughing, no doubt, at Starmer from back home as they continue full steam ahead unashamedly expanding their oil and gas output, increasing their energy production and growing their manufacturing base.

I had a meeting last week with the UK's chemical industry leaders where they explained to me how a combination of high energy prices, environmental regulation and carbon prices were killing the sector and, worse still, destroying critical supply chains and making us dependent on China for chemicals for even the most basic of things like purifying our water.

Starmer needs to wake up to the dangers of not being able to have reliable, affordable energy and stand up for our national self-interest.

Even the EU is watering down its Net Zero commitments, such as the ban on sales of new petrol and diesel cars. No wonder no other countries at all signed up to Starmer's 'Clean Power Alliance' last week, in yet another humiliation for him.

We have already lost our primary steel making capability. Scotland has lost its only oil refinery and we are now set to lose our chemical industry. It's heartbreaking for the people losing their jobs, and a self-sabotage of our national interest.

How ironic that Labour used to be the party that championed heavy industry and the working-class, whereas now it's consigning those workers to the dole queue.

Starmer's legacy will not only be to have been the destroyer of manufacturing in the UK, but the person who finally broke once and for all the link between the Labour Party and working-class voters.
