Her remarks, made in the opening address at the Art Business Conference in London last week, will be a welcome boost to a market concerned at the threat of increasing government interference.
Referring to the Artist's Resale Right Regulation of 2006 as "not working in our favour" and certain changes to copyright law as "quite mad", she declared the industry needed to work together to fight "further idiocies".
Borwick, who was elected member of parliament for Kensington in May this year and appointed president of the British Antique Dealers' Association (BADA) in July, said it was her mission to ensure colleagues in Westminster "understand the importance of the art and antiques industry and do not impose further ill-considered regulation".
Talking to ATG after her speech, she said she was open to representations from both individuals and trade bodies: "If legislation is coming up, people can tell me about its possible effects and unintended consequences."
She referenced the Conservative party's manifesto pledge to "press for a total ban on ivory sales".
Borwick looks set to become a key voice for the trade in the years ahead.
She told ATG she has already had constructive talks with the Society of London Art Dealers and received a positive letter from LAPADA chairman Lord Chadlington two weeks ago.
Borwick urged the industry to unite to promote its activities and to ensure it does not get sidelined.
The art and antiques sector is "an important industry and that's very much the message we need to get across", she said.
