Known as Olivia Allison before her marriage to Roberto Federici in the summer of 2011, she is the British team’s longest-serving member along with Jenna Randall.
She was paired with Randall for the Melbourne Commonwealth Games in 2006 before winning silver in the duet with her four years later in Delhi.
Federici made her World Championship debut in the same city as her Commonwealth Games bow in 2007 – the same year the British High Performance Centre opened in Aldershot.
Federici and Randall became the first British synchronised swimmers to compete at an Olympics for 16 years in Beijing in 2008, placing 14th in the duet.
She learnt to swim when she was three and followed her elder sister Alex in taking up synchro as a youngster – Portsmouth Victoria where she first began.
A fan of multiple MotoGP world champion Valentino Rossi, Federici’s Olympic hero is Jesse Owens, who won 100m, 200m, 4x100m relay and long jump gold at the Berlin Olympics in 1936.
