The presiding judge in the Michaela McAreavey murder trial has instructed the nine-member jury to disregard all the questions he put to one of the defendants during court proceedings last week.

He also told the jury to disregard all answers given to those questions by Avinash Treebhoowoon.

The judge ordered that all the relevant references be expunged from the record.

The development follows legal discussions last Friday and again this morning.

A defence lawyer had raised issues about the way the trial was being conducted.

Explaining the background to his directions this morning, the judge told the jury that a point of law had been raised.

He said it was a very technical issue and that he did not want to go into it in detail.

Today is the start of week seven of the trial, with two hotel workers accused of murdering Mrs McAreavey while she was on honeymoon with her husband John.
