Driving through Gaza is like "driving through the ruins of Hiroshima, or Stalingrad, or Dresden"

Tom Fletcher has been the United Nations humanitarian chief for almost a year and speaks to Nick two weeks into his organisation's efforts to get as much aid as possible into the Gaza Strip.

He gives a behind-the-scenes account of how he works with the Trump White House and how the ceasefire deal was struck in Sharm el-Sheikh.

Fletcher also shares his lessons learned from his years as foreign adviser to Tony Blair, Gordon Brown and David Cameron.
