SEOUL (Reuters) – Prime Minister David Cameron joked on Thursday that getting away from home for the G20 summit would allow him to catch up on his sleep after the birth of his baby daughter.

“Everyone else has come to Korea for a summit or a business meeting. I’ve come just for a good night’s sleep,” Cameron told delegates at a business summit.

Cameron and his wife Samantha had a daughter, Florence, in August and also have two other young children.

Cameron is on a gruelling five-day trip which began with an overnight flight from London and a 36-hour visit to China.

The prime minister, who has a quick wit, earlier joked that he was spending more time at the summit promoting England’s bid to host the 2018 World Cup than he was on core G20 issues.
