Mairead Philpott, wife of Mick Philpott, is being questioned by her defence lawyer. She is warned that she is likely to remain in the witness box for some time.
Did you light the fire? "No". Did you help anybody else start the fire? "No". Did you see Mick or Paul start the fire? "No," Mairead says.
Would you do anything which would result in you spending the rest of your life without your children? "No".
Would you take part in anything that would harm your children or risk harming your children? "No".
She tells the jury that she was badly "abused" by her father when she was three or four years old, and that she was raped while on holiday as a teenager.
New witness, George Cobbledick, begins giving evidence for the defence.
Mr Cobbledick – who is the cousin of Mick Philpott – is testifying from behind a screen covering the witness box.
The jury is being shown a video of Mick Philpott giving a statement to police after the fire at his home which killed six of his children.
He describes hearing the fire alarm and how the fire looked like a bright orange "disco light".
Mick Philpott tells the jury he didn't tell police that his friend Paul Mosley had had sexual relations with his wife Mairead because he was "ashamed".
He also told the court he felt it had no relevance to what had happened to his children on the night of the fire.
Mick Philpott is in the witness box at Nottingham Crown Court explaining how traces of petrol got on his clothes.
He says the fuel had spilt from a petrol grass strimmer that he had lent to his neighbour Adam Taylor.
Mick Philpott is to continue giving evidence in his manslaughter trial over the deaths of six of his children after a fire at his home in Derby last year.
Mick and his wife Mairead Philpott appear alongside Paul Mosley charged with manslaughter following the fire on May 11, 2012.
Mairead is expected to give evidence to the court fro the first time today.
All three deny the charges.
As Mick Philpott describes to the jury how he felt about seeing his children in the mortuary at the Royal Derby Hospital, a shout of abuse comes from the public gallery.
The Judge Justice Thirlwall tells the court that anyone making further outbursts will be removed from the courtroom.
Under cross-examination Mick Philpott denies starting the fire at his home on Victory Road, telling the prosecutor Richard Latham QC: "You can try to blame me as much as you like. But you've got the wrong two people."
When asked by the prosecution who had a grudge large enough to set fire to his house & kill his children, Mick Philpott tells the jury "I don't know. A lot of People had a grudge against me."
Mick Philpott has admitted hitting a previous girlfriend, but says she deserved it because he claims she hit his children.
Prosecutor Richard Latham claimed Philpott hit his mistress, Lisa Willis, with a stick.
Philpott says he "can't recollect" whether he did or not.
