A spokesperson for the couple confirmed the sad news with a short message which read:
"Tragically Marina and Ben Fogle have lost their precious baby at 32 weeks gestation. Marina is still in hospital.
"They are obviously devastated and would appreciate their privacy at this terrible time. They thank you for your understanding."
TV presenter Ben and Marina are parents to son Ludo, four, and daughter Iona, two. Marina had a miscarriage before Ludo was born.
We interviewed Marina in May, when she told us Ludo and Iona were 'so excited' to be having a new sibling.
"They are so excited about a baby," she said. "Ludo couldn't believe his ears when we told him. He was a bit young to understand when I was expecting Iona but he gets it this time around.
"We didn't want to share the news with them until the 12 week scan, but when we did it was so special.
"Ludo naturally gravitates towards babies – human and animal - so he is beside himself at the thought of a baby."
Our sympathies to Ben, Marina and their family.
