Build into UK law the new EU tax avoidance laws whether UK Is part of EU or not.

it is rumoured that Brexit was backed up by some big fortunes to avoid having to comply with the new EU tax avoidance laws. Embracing these laws will benefit the whole country and will ensure a fairer system that does not favour the privileged classes. And would put these rumours to rest, right?

We can't accept your petition because the EU Anti-Tax Avoidance Directive came into force in UK law and across the EU on 1st January.

We're therefore not sure what action you would like the UK Government or Parliament to take.
You can find out more about the Directive here:
