(6)Competent authorities should have a minimum set of investigation and enforcement powers in order to apply this Regulation, to cooperate with each other more quickly and more efficiently and to deter traders from committing infringements covered by this Regulation. Those powers should be sufficient to tackle the enforcement challenges of e-commerce and the digital environment effectively and to prevent non-compliant traders from exploiting gaps in the enforcement system by relocating to Member States whose competent authorities are not equipped to tackle unlawful practices. Those powers should enable Member States to ensure that necessary information and evidence can be validly exchanged among competent authorities to achieve an equal level of effective enforcement in all Member States.
