Obama defeats Clinton in Wyoming
Barack Obama campaigns in Wyoming on Friday
Some momentum now returns to Mr Obama after earlier defeats
Barack Obama has won the contest for the Democratic presidential nomination in the state of Wyoming, defeating his rival Hillary Clinton by 61% to 38%.

He remains ahead in the overall contest in terms of delegates but is trying to regain momentum lost last week when Mrs Clinton won Texas and Ohio.

Wyoming sends 12 delegates to August's Democratic convention, making it one of the smallest prizes in the race.
