Here are some quotes from it:
The role of postal market regulation is not to create competition, but rather to
create a framework that allows for competition. Regulators that today set out
to create a high level of competition within a short period of time have failed
to understand the postal market correctly.
2.4 billion items are inserted by competitors into
the network of Royal Mail, while only 35 million
items are distributed by themselves.
Thus, only around 0.8 percent of the competitors
volumes generate additional value and investments
in the UK market
Where postal regulation remains, it must focus on end-to-end services;
rule-setting for downstream access is an inadequate approach.
