Newsflash, you don't get to decide what the Welsh spend their money on.
Don't make out it's a handout - we pay our taxes - we also fund all the government services in London. Do you think the English wouldn't want NI, Scotland, or Wales if we weren't a net benefit to you?
Whilst we're at it, stop spening public money on all the English orientated vanity projects, such as overpriced fixes to the "palace" of westminister, HS2, fictional garden bridges over the thames. ETC.
By your logic, the museums in London, St Georges day celebrations, etc.should stop being funded... As should all the other wasteful English "culture" spending that goes on (mainly in south east england)
Also, why should our license money be wasted on the jingoistic proms?
