Highly unlikely TTT !
The Tories are about as popular in Wales as a Rat Sandwich, as a previous Leader of Plaid Cymru said a few years ago
( actually, he was referring to John Redwood when he was foisted on us as Governor General by the Tory Party in Westminster, which even other Tories had to agree with ....He wasn't even a Welsh Tory MP ! )
First of all, the Tories would have to gain overall control of the Welsh Assembly Government, of which there is no sign whatsoever at the moment.
At present, the Tories hold just 14 seats out of a possible 60, with Plaid Cymru coming a close third with 11 seats. In 2011, Labour gained a significant amount of seats and currently hold 30.
Also, the Welsh Tories hold just 8 seats at Westminster, out of a total of 40.
So, if the Tories are suddenly going to become suddenly awfully popular, they have a great deal left to do. This "bribe" that they are promising won't fool the Welsh, anymore than previous promises did.
