I have to say I'm with vj32 here. It's astonishing that parents of children who got hundreds of pounds from the Government are now complaining that this has breached their children's human rights.
There are plenty of children's savings/investment schemes available if you can't open a Junior ISA, and you don't even need a specifically children's one, as pretty much any investment can be wrapped in a bare trust which will make it the legal property of the child.
The Junior ISA was basically the Government realising that it had thrown the baby out with the bathwater when it scrapped CTF vouchers. It couldn't just say people could open CTFs with their own money, as CTFs were a Labour idea. Exactly the same as when Labour introduced ISAs to replace the 'Tory' PEPs.
The two are bound to end up under the same regime eventually, just as PEPs and TESSAs came under the ISA regime, but having shot themselves in the foot to start with, the Government in trying to salvage the situation has given the industry almost no time to get the JISA up and running, and integrating the two systems will take a little longer.
