Perri Shakes-Drayton third in 400m hurdles semi-final

Team GB's Perri Shakes-Drayton will have to wait to see if she qualified for the final of the women's 400m hurdles.

Having got out of the blocks well, 23-year-old Shakes-Drayton gave herself every chance of finishing in the top two of her race.

However, she could only manage to finish third in a time of 55.19s.

She must now wait to see if she has made the final as a fastest loser.

Lashinda Demus won the race, while Kaliese Spencer came second.
