Sex And The City star Kristin Davis was left choked up during an emotional interview about her time at the Dadaab refugee camp in Kenya.

The 46-year-old, best known for her role as Charlotte York Goldenblatt in the US show, unsuccessfully tried to stop herself from sobbing as she spoke about her trip as an Oxfam ambassador.

Speaking to BBC Breakfast's Bill Turnbull and Sian Williams on Monday morning the actress dabbed her eyes as she described her journey to the refugee camp where some 380,000 are sheltered after fleeing drought in neighbouring Somalia.

The star had been traveling in Tanzania with Oxfam at the weekend but decided to visit the Dadaab camp after hearing of the number of people arriving there - some 1,300 a day according to the charity.

Kristin explained: "We were really unprepared for how shocking it is. I think the main thing that struck me was how desperate their situation was that they left.

You would never come to this place if you weren't in absolute desperate need because it is in the middle of nowhere, it's extremely windy, hot, there's nothing there but the camp. "And the camp is so overfilled that a lot of these people, who are mostly women and children, have walked 20 days they have lost family members along the way... I might cry," Kristin said as her voice cracked.

But she was unable to contain her tears she explained the plight of one disabled Somali woman who had lost two of her five children and her husband on the way to the camp.
