Just tuned in to GBBO?
Peter wins.
Bad luck - you missed me by 15 minutes and my phone was charging in a different room. I doubt I would have been tempted to look at Mumsnet in any case - dh always 'fast forwards' over the adverts and it was the GBBO Final after all - I do have some self control.

The tariff for South African peaches is 4.9%, not 18.4%.
Southern African peaches? You might be right, but I'm not going to do the legwork to check, and you haven't provided a link. Is the tariff the same for processed peaches? Is there a tariff rate quota? You don't have to answer - I don't even buy tinned fruit.

Voldemort's division between mud bloods and pure bloods come to mind
Actually, I have two French grandparents (who emigrated to the UK in their early twenties) - which I believe makes me one quarter French - but alas my French language skills are very limited. DS1 has 3 language GCSEs though (A*s/9s).
Anyhow, I'll say this...Clav you are making another frivolous and unsupported argument wrt Erasmus+...A case of confirmation bias without the confirmation. One, this conjecture that the target group is smaller than you not we think is plain wrong.
I know that 26% of the UK Erasmus cohort in 2014/15 were not UK nationals and 1,000 students were double counted because they attended more than one placement in the same year - circa. 5,000 fewer British students (out of 16,500/17,000) than we thought.
Anecdotally, 6 out of 9 undergraduate students I know personally, who are currently studying a degree with a European language element, grew up in a bilingual home in the UK - but that might be because my dc attend private schools in the West London/Surrey area.
Also from the 2014/15 cohort;
^"90 percent of European language students take part in Erasmus and they constitute as many as 41 percent of all Erasmus students. Looking at all language students together, they constitute 50 percent
of all Erasmus students even though they represent just 6.4 percent of the graduate population. This high concentration of Erasmus mobility among language students is another special feature of the UK."^
It seems that you're implying that it'd be better to deprive some 'pure bred' British youth of having this amazing experience, rather than see some undeserving bilingual but still British students share in the experience.
Actually, I was just musing on the low take up of Erasmus/Erasmus+ among British students - and wondering why they had not been encouraged to participate in greater numbers before the Brexit vote. Saying that, I think the UK government will probably agree to participate in the scheme (or something similar) in one form or another.

We have never, in 15 years, had a French student come to France on Erasmus. Why the hell, if they have gone through the process of settling in the UK to study and can get financial aid and access to study programmes in another country, would they then mooch back to France?
It sounds as though some students want to do that - University of Sussex;
"Note: EU students completing a placement in their home country have a lower funding priority than those students completing a placement in another European country."
