Why have they left it until this late to try to kill the TPD regs?
I expect the RCP report kicked it off. To have such a well-respected medical institution come out on the side of vaping probably made them sit up and take notice.
I think this has played a factor, but I'm willing to bet it would still have gained little traction without the impending EU referendum. Those wanting to leave see it as an ideal example of how the EU thrusts bad laws onto its members - and the ability to embarrass Camoron into the bargain.
Also, on the back of yet another U-turn by the government, they are coming across as increasingly spineless and unable to make legislation proceed from idea to statute. Even those who with to remain in the EU see this as a vehicle to slap the Tories. Given fair wind, it might just work.
