A South African judge is reading her decision on whether she will dismiss the murder case against a British man accused of killing his wife while they were on honeymoon.

Cape Town High Court Judge Jeanette Traverso was expected to announce her decision later Monday after explaining her reasoning to the court. In her lengthy reading, she has said the testimony of the prosecution's main witness was riddled with contradictions.

Businessman Shrien Dewani is accused of arranging the murder of his wife Anni in 2010.

Dewani says she was killed during a botched carjacking. The state's key witness, Zola Tongo, says Dewani paid him to hire two men to carry out the murder.

Dewani's lawyers have argued that the case should be dismissed due to a lack of evidence.
