London – Britain's Olympic heptathlon champion Jessica Ennis-Hill is pregnant and will miss the Commonwealth Games in Glasgow in July, she said on Friday.

The 27-year-old confirmed she is expecting her first baby later this year but hopes to defend her Olympic heptathlon title in Rio de Janeiro in 2016.

In a media statement she said: “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 - that challenge really excites me.”

Ennis Hill won the Olympic title in London in 2012 to add to her world crown in 2009 and her European title in 2010. – Reuters
