Portrait artist Tess Barnes is bringing a colourful exhibition of 50 well-known British women to Oxford.

The 50 Women of Substance show is at Wolfson College until May 9.

It showcases portraits of some of the UK's most well-known and highest achieving females, celebrating their contribution to society, arts, literature and science.

Subjects include TV presenter Carol Vorderman, fashion designer Zandra Rhodes and singer Beverley Knight. Well-known Oxfordshire women include scientist Susan Greenfield and chef Sophie Grigson.

Ms Barnes, who grew up in Headington and attended Wychwood School, said: "I started these paintings about 14 years ago when my first daughter Emma was born and I felt a special affinity with womenkind.

"My first portrait was of the judge Nina Lowry, who I met when I was working as a barmaid opposite the Old Bailey.

"Catherine Hughes, the principal of Somerville College, was my second portrait and I soon got the idea that I could develop a series. Now that I'm 50 I've completed my 50th portrait."

Ms Barnes chose the Breast Cancer Haven, set up in 1997 by Sara Davenport to offer free support, information and complementary therapies to anyone affected by breast cancer, as the benefiting charity for the launch of the exhibition and tour venues.

Ms Grigson said: "I love the way Tess captures the warmth and intelligence of her subjects, finding their humanity when so many others may only see the successful, slightly scary exterior."

Ms Barnes studied at the Chelsea College of Art and Goldsmith College, and has twice been selected for the BP Portrait Award.

Her work has been shown at The National Portrait Gallery, The Royal College of Art, The Saatchi Gallery and Mall Galleries.
