Action at the PostFinance Arena is set to start with a day of junior qualification, followed by the senior qualification on Thursday (June 2).

The junior all-around final is scheduled for Friday (June 3), while the senior team final is penned in for Saturday (June 4).

Competition will conclude on Sunday (June 5) with the senior event finals and junior event finals.

At last year’s World Championships, Great Britain knocked Russia off the podium to finish third behind winners United States and runner-up China, and win their first-ever medal.

Both teams are expected to run each other close for top honours in Bern with Britain relying on sisters Becky and Elissa Downie, who are joined by Gabby Jupp, Claudia Fragapane and Ruby Harrold.

Russia are sending Daria Spiridonova, the reigning uneven bars world and European champion, as well as defending floor exercise European champion Ksenia Afanasyeva and three-time continental gold medallist Aliya Mustafina.

They are flanked by Angelina Melnikova and Seda Tutkhalyan, both of whom helped their country claim the European junior team title in Bulgaria's capital Sofia in 2014.

The battle for bronze appears quite open with the absence of The Netherlands, who are only sending two gymnasts, and Germany and Italy resting their best gymnasts.

France are expected to have a good chance, fielding a team including Marine Brevet, Loan His and Marine Boyer.

The home nation are led by 2015 European all-around champion Giulia Steingruber, while Belgium will test first-year senior Nina Derwael who is returning to competition after a hand injury.

Romania will be looking to redeem themselves after not qualifying as a team for this year’s Olympic Games, but plagued by injuries, their biggest chances are on beam and floor through the experienced Catalina Ponor.

Individual stand-out names include the likes of Greece’s Vasiliki Millousi, Hungary’s Zsofia Kovacs, Portugal’s Filipa Martins, Germany’s Kim Bui, Italy’s Martina Rizzelli and Spain’s Ana Perez.

In the junior category, a battle is anticipated between the teams from Russia, Britain, Italy and Romania.  

Italy’s Martina Maggio and Francesca Linari are among the names to watch out for along with Romania’s Ioana Crisan and Olivia Cimpian, Russia’s Elena Eremina and Anastasia Iliankova, and Britain’s Lucy Stanhope and Maisie Methuen.

Germany, meanwhile, are sending Helene Schaefer, the older sister of world beam bronze medallist Pauline Schaefer.
