Pentathlete Mhairi Spence celebrates her world title victory

British modern pentathlete Mhairi Spence launches into a breathless celebration as she wins the world title in Rome.

Spence, 26, earns herself a place at the Olympics by virtue of the win, as does team-mate Samantha Murray, who came third. They are expected to be confirmed as members of Team GB next month.

Spence and Murray are joined by Pentathlon GB performance director Jan Bartu, who describes how the two "transformed" into Olympic medal contenders.
