One for and one a little bit against. Thanks for the reply Anthony. People more knowledgeable than me would argue the toss with you but there seems to be some evidence now that kids that have had a bi-lingual start in school soak up other languages at a faster rate.
These languages also represent cultures that exist side by side with the UK's english speaking culture, often they can be invisible as all the native-speakers also speak english - you could visit the Highlands and Islands and perhaps never hear Gaelic because the natives will speak English to you. I personally think that compared to the dosh we chuck away to Euro-criminality, a little bit more to help the Celtic languages would do no harm in the long run. After all they were around before English really emerged INTO phpbb_what it is today. It is a pity schools in the rest of the UK didn't at least let the kids take a look at the Celtic languages but I take your point about learning - did you say French?
No doubt UKIP will produce a manifesto in Welsh and perhaps Gaelic like most parties do and may even have Welsh speaking candidates?
A final thought, in Scotland support for gaelic is cross-party, there is a vocal minority against but there is a huge community of interest behind the language even though native speakers now represent only 1% of the population.
