Davies joins the trade body from the Conservative Party where she was special advisor to shadow home secretary Chris Grayling. She has also worked as a policy advisor at the Federation of Small Businesses and as a Home Office analyst.
Davies replaces Stephen Hogg who is returning to the civil service having been on secondment from the Home Office since 2006.
WSTA chief executive Jeremy Beadles said: “Laura brings valuable experience of working with businesses and in the political world and I am confident she will be a real asset to the WSTA.”
He added: “I’d like to thank Stephen Hogg for his valiant efforts on our behalf. He has worked tirelessly to promote the role industry can play in alcohol policy and has helped establish Community Alcohol Partnerships as a model for tackling alcohol misuse and associated anti-social behaviour at local level.”
