ANNI Dewani, who was killed on her honeymoon, went to a doctor before she left because she was planning to get pregnant, a court has heard.

Francois van Zyl, the lawyer representing British businessman Shrien Dewani, told the Western Cape High Court that he had medical notes which showed she visited the doctor on November 4, 2010 and told him she was trying to conceive.

Mrs Dewani was shot dead as she and her new husband toured a rough Cape Town neighbourhood in a taxi in November 2010. Mr Dewani is now on trial for her murder.

Prosecutors say that the bisexual entrepreneur, from Westbury-on-Trym, near Bristol, was leading a secret double life and had arranged a staged carjacking-gone-wrong in which his wife would be killed to get him out of his marriage.

Mrs Dewani had told the doctor she was not on contraceptives, and the doctor advised her to take tablets to improve her fertility, Mr Van Zyl told the court.

Cross-examining Mrs Dewani's cousin and prosecution witness Sneha Mashru, Mr Van Zyl said this made her evidence about a rocky relationship strange.

"I have to put it to you that what she told the doctor, that she wanted to become pregnant, that she wanted to get medication, flies in the face of what you told me about divorce," he said.

Ms Mashru repeated that when Mrs Dewani came back from her wedding in India, she spoke to her about not wanting go on honeymoon.

Dewani, 34, is accused of the murder of his wife during their honeymoon in Cape Town in November 2010. He has pleaded not guilty to the five counts against him. The prosecution alleges he conspired with others to stage the hijacking.

The trial is expect to last to at least until December.
