Hi....i could be wrong, but to me it reads as three parts:
1) R&D across UK and Spain
2) actual manufacturing in UK and Spain
3) investment in the Spanish facilities to make them greener....(not especially to manufacture the car)......
The autocar clip gives reference to the UK getting the majority of the grant and thus I guess we are getting more of the R&D and more of the manufacturing whereas the Spanish plant are getting more green aspects.
Could be very wrong......I think though more detail will come out in due course so we will get to know much more then....it will become clearer!! but in any case...the UK gets more investment!!!!.......that has to be good news!!!!!......well done mandy!
