Pregnancy is "unexpected but exciting"

The 27-year-old from Sheffield, who married long-time partner Andy Hill in Derbyshire last May, is expecting her first child.

She said in a statement: "I have some very unexpected but exciting news to share - Andy and I are expecting a baby.

"We are completely overwhelmed, with excitement and a degree of anxiety that I am sure all first-time parents will relate to.

"My plans for 2014 have been completely turned upside down, but having had a couple of weeks to think about things from a career point of view I am 100 per cent set on returning to full-time athletics once our baby is born and go for a second gold medal at the Rio Olympics in 2016.

"But in the short term I will make our baby a priority and enjoy the whole experience as much as possible.

"I am sorry I won't be in Glasgow for the Commonwealth Games, but know it willbe an amazing occasion. I will be at home awaiting the arrival of a little Ennis-Hill."
