FC Britannia XI

The club was previously known as Britannia FC and was previously one of the more dominant sides in Gibraltar, winning several championships in the 1950s, until going into administration and regrouping under its current name in 2009. In 2014 they secured promotion back to the Premier Division after winning the Second Division title. Their first season saw them avoid relegation due to the league's expansion. The club began their second season in the top-flight well under Alan Arruda, being third for the majority of the first half of the season. However, his resignation in early 2016, coupled with the departure of key players, saw them plummet down the league and finish in 9th, meaning they had to participate in a play-off to determine their fate. After losing their play-off to Mons Calpe, they resigned from the league. Britannia returned to football in 2023, joining the Veterans ShieldPlay League for retired players.
