Great Britain added five more gold medals to their haul on day eight at the Rio 2016 Paralympic Games. Sophie Christiansen won her seventh Paralympic gold medal in her dressage event, defending the Grade 1a championship title she won in London four years ago.

British teammate Anne Dunham took the silver medal with a second place finish.

Natasha Baker continued GB's dominance of dressage events. She scooped gold in her Grade II event having secured the best score on all five of the judge's cards, defending the title she won in 2012.

There was more success for Great Britain at the Logoa Stadium where Jeanette Chippington marked her return to the Paralympics with another gold medal in the KL1 canoeing event. The 46-year-old starred in five consecutive Games from 1988 to 2004, claiming 12 medals in swimming events, but returned after a 12-year hiatus to become the latest Briton to win two golds in two different sports.

Chippington led a treble success in the canoeing on day eight with Emma Wiggs winning the KL2 final and Anne Dickins taking gold in the KL3.

Their successes take Great Britain's gold medal haul to 49 and a 50th will be guaranteed on Friday when Gordon Reid and Alfie Hewett meet in the wheelchair tennis final.

Elsewhere, Kadeena Cox narrowly missed out on her third gold medal in Rio, settling for silver as part of the T35-38 4x100m final, with China taking first place.

Richard Whitehead, having already won gold in the 100m T42 final was unable to add another after finishing second in the 200m event. And after finishing sixth in the T54 800m, six-time champion David Weir confirmed his plans to retire from the track after this summer's Games.
