The four home nations also field national sevens teams. England, Scotland and Wales are all "core teams" that compete in all events of the annual World Rugby Sevens Series for men, and England have been a core team in the World Rugby Women's Sevens Series since the latter competition's creation in 2012. Ireland have not been as competitive in men's sevens, but the women's sevens team have had core status alongside England on two different occasions—first for the 2013–14 series, and most recently since the 2015–16 series. The United Kingdom currently hosts an event in each (men's) World Sevens Series in London; the UK had also hosted a second event in Scotland, but that event was removed from the schedule after the 2014–15 series. The 2014–15 women's series saw the debut of a London event, but that tournament did not return in any subsequent series. Rugby union returned to the Olympics in 2016 with sevens tournaments for both men and women; the Great Britain men's team won the silver medal, losing to Fiji in the final, and the women's team lost in the bronze medal match to Canada. In a contrast with football, the participation of Great Britain sevens teams at the Olympics was endorsed by World Rugby (then known as the International Rugby Board) in 2011. In the Rugby World Cup Sevens, the men's teams of England and Wales have both been victorious—England in the inaugural tournament in 1993 and Wales in 2009.
