I'm guessing Ian is referring to those of working age who don't work, but could do so?

Does not really mean a lot to the average UK national
They do not know what that means !
Need to break it down in real terms.
I remember an old retired school maths teacher friend who was asked to support in a not so well performing school/class. She struggled in the first couple of weeks and was stuck about how to get the kids to behave, listen and hopefully learn.
Long story short she started using examples which actually translated to what he kids understood, ounces, 1/8th, grams, score, bobby etc etc. She had better success using this method.
So GDP, National Debt, Defecit etc etc means diddly squat to a large voting population.
Instead terms such as immigrants taking your jobs, EU taking away your powers translates and means something which they can better comprehend.
I also remember getting into a heated debate with a sub-contractor whom my builder used but had not paid yet.
Upon turning up at my premises and making his way round the back I tried to explain to him that I had paid the lead contractor whom I had a contract with and he needed to take the issue up with him. After some serious exchanges, police were called and he walked away, only to return again in 10 mins and confront my wife and young kids around - Police were notified again and this happened a few times - Eventually an officer told me the main problem was the way I spoke - the sub-contractor thought I was belittling him with my use of phrases - instead he was used to geezer, mate, dough etc etc.

So to win votes a politician needs to look at the make up of voters and speak to them in a language they understand or take measures to bring up the population to a level so they can understand real issues.

However history has shown us that leaders do not want the latter and it is why many politicians on the fringes get bursts of power and acceptance when they pull on a small but explosive thread and then let the snowball and herd mentality do the rest. Then over time they move back to centre ground as real people start to put out the flames and start to quell these extreme ideologies who are not really interested in the well being of the people, rather the power that comes with it.

Nobody has suggested that and it isn't going to happen.

I'm not sure it matters who is Tory leader, what can they offer after 14 years that the voters will believe. Most things have continued to get worse, the highest tax burden, falling GDP per capita, failing NHS, an enormous increase in immigration while they have let millions of Britons live off other peoples' labours. Reform are a serious and possibly (hopefully) existential threat to the Conservative Party.

Apparently, British pensioners living in Europe are set to keep the winter fuel allowance while those at home will lose the payment. Expats living in the European Union plus Norway, Iceland, Liechtenstein and Switzerland are guaranteed the allowance by the Brexit withdrawal agreement.
