Olivia and Jack are the most popular names in Britain for babies born in 2008, according to a survey published today.

The female Christian name reclaims the top spot from Grace after just 12 months. Grace — made famous by the Hollywood screen siren Grace Kelly — slipped back into third place behind Ruby, the name of singer Charlotte Church's baby daughter.

Jack has been top for 14 years since it took over from Thomas. This year Jack only just managed to retain its place despite stiff competition from Oliver, according to the UK parenting club Bounty, which conducted a survey of 380,000 babies born this year. Emily, Jessica, Sophie, Chloe, Lily, Mia and Lucy completed the top 10 girls's names.

The biggest movers were Isla, which climbed from 58th to 35th and the 1960s-inspired Summer, which climbed 28 places from 44th to 16th. Ava — the name of Myleene Klass's daughter — also leapt 15 places to 19th.

The troubles of the singer Amy Winehouse perhaps had an effect on the popularity of the name, with Amy dropping three places to 23rd, though Blake — the first name of Winehouse's husband, Blake Fielder-Civil — appeared in the top 100 for the first time.

Holly, the name of Davina McCall's and Richard Branson's daughters, is clearly suffering from fatigue, dropping six places to 25th. Rebecca is also on the wane, falling from 32nd to 48th, as is Courtney, which fell 16 places to 88th.

Theo, obviously inspired by England's teenage football hero Theo Walcott, is among the biggest climbers in the boys's list, rising from 70th to 58th.

Faye Mingo, of Bounty, said: "The Bounty baby name poll shows parents are continuing to be creative and inspirational about the names they choose for their children. "Some parents want a name that's totally unique, and names such as Zebedee, Selim and Zenon are now emerging and growing in popularity. Others are simply breaking with convention and becoming bolder in their choice of names."

Biblical names such as Samuel and Matthew remain popular but Mark, Luke and John have fallen out of favour, while names like Joshua, Jacob, Noah and Isaac are becoming their contemporaries.

"Boys's names have witnessed the biggest changes over the last decade as parents are increasingly influenced by American culture and celebrity trends," said Mingo. "Whilst Barack may be growing in popularity in America, British politicians don't influence our choice of names in the UK. Traditional royal names continue to reign supreme in the boys's top 100."
