An Australian cardiologist committed to stand trial in Uganda over his wife's murder is again seeking bail.

Dr Aggrey Kiyingi has applied to the Ugandan High Court for bail on the grounds of poor health.

Through his lawyer Mubiru Nsubuga, Kiyingi told Justice Remmy Kasule he suffered high blood pressure, backache and that at 51 years of age he could not cope with prison conditions.

He said that it was his constitutional right to be granted bail, adding he was a man of dignity with a lot of property in Uganda and so could not flee.

Justice Kasule said he would rule on the bail application on January 18.

On Wednesday Kiyingi was committed to stand trial on a date to be fixed over the murder of his wife Robinah Kiyingi last July.

Ugandan state prosecutor, Vincent Wagona, told the Buganda court the prosecution would prove that Kiyingi plotted Robinah's murder and that he asked various people to help him kill her.

Wagona said that on the night of July 11, 2005, Robinah Kiyingi was returning home alone when she was shot dead in her car. A short time later, Kiyingi called the killer from Australia to find out whether the mission was successful, he said.

Kiyingi was earlier refused bail. In September, a judge refused his application saying the cardiologist had surrendered only his Australian passport, not his Ugandan one which police believed he had hidden so he could use it to flee the country.

Kiyingi is being held at Luzira Prison.

Last month he was admitted to hospital at Mulago in critical condition.

If found guilty Kiyingi could be sentenced to death or life imprisonment.
