With her husband Darren Bennett she has been competing as an amateur since July 1997 and as a professional since May 2003. The couple has achieved considerable success in the Professional Latin style of dancing, both nationally in the UK and internationally.
Lilia Kopylova started ice skating aged four, winning the title of Junior Moscow champion aged nine.
In 1987 she started training as a dancer. Her first dance partner was Mikhail Botashev, a Danish champion, and in 1990 they won a Lambada competition; and a year later, they were the first Soviet pair of their age to be allowed abroad to dance. They won the 1990 Danish Open in Copenhagen, followed by success that same year in France and Italy.
In 1994, Kopylova represented Russia in the International dance championships in Denmark. In 1997 she was introduced to Darren Bennett and five months later, having moved to the UK, they won the International and British amateur Youth Championships in July 1997. The couple turned professional in 2003, and are now regarded as one of Britain's finest Latin American dance couples and make regular appearances on British TV. Lilia's favourite dances are the rumba and the foxtrot.
In November 2005 Bennett and Kopylova won the British Championships for Professional Latin, coming first in all five dances. In November 2006 they successfully defended this title against a challenge from Olga Rodionova and Paul Richardson, who had previously been competing for the USA but had recently registered as a British couple. Bennett and Kopylova eventually triumphed, again winning all five dances to retain the title.
Other competitive highlights include winning the Rising Star professional Latin title of Blackpool Dance Festival in 2003, and reaching the final of the professional Latin competition in the 2005 Blackpool Dance Festival.
In February 2008, Bennett and Kopylova were winners of the Carl Alan Award for Ballroom, Latin and Sequence (performers)- a prestigious title described by the IDTA as 'the Oscars of the world of dance'.
Bennett and Kopylova are part of the team behind the "Essentially Dance", a scheme for British children to learn ballroom and Latin American dance, in a bid to tackle childhood obesity and promote social skills. Funded by the Aldridge Foundation and launched on June 22, 2009, it was filmed and produced by Winning Pitch TV.
The couple are currently starring in a West End dance show, Latin Fever, which they have choreographed themselves, as well as choosing the music and costumes to reflect the mood of each Latin dance.
In Autumn 2004 she competed in the BBC One pro-celebrity ballroom dancing television programme Strictly Come Dancing, dancing with celebrity singer Aled Jones. They finished fourth overall and fourth in the following Christmas Champion of Champions show. Her husband Darren won both shows with Jill Halfpenny.
Lilia won the 2005 series, partnered with Darren Gough, who was the first male celebrity to win the title. The couple went on to win the Christmas Champion of Champions trophy, including a dance with a perfect score of 40 out of 40. The show featured couples from the 2004 and 2005 series, as well as Rachel Hunter and Evander Holyfield from the US version of the show, Dancing with the Stars.
Lilia participated in the fourth series of the show partnered by Matt Dawson a former England Rugby Union scrum half. They were runners up, losing to Mark Ramprakash and Karen Hardy. This result made Lilia the first, and as of 2009, the only professional dancer to make it to the top 2 twice. In the Christmas Special that year they were the only couple from series four to receive a perfect ten from the judges.
In Series Five she partnered presenter Dominic Littlewood. They were eliminated in the fifth round of the competition. She was also reunited with her Series Three partner Darren Gough for the 2007 Christmas Special, in which they received another perfect score for their American Smooth, and won the competition.
