Gordon Brown has failed to say whether Attorney General Baroness Scotland will stay in her job amid reports that she has been found in "technical breach" of rules on employing migrant workers.

Mr Brown said he would have to see the report on the case and hear what Lady Scotland, who grew up in Walthamstow, has to say following a BBC report that she is expected to be fined after employing a housekeeper from Tonga who did not have the right to work in the UK.

"I will have to see the report, I will have to look at it, I will have to see what they actually say. The question is whether she knowingly did not look at the passport or the documents of the person that she was employing or whether she did do that but she did not keep a copy of the documents," he told GMTV.

"We will have to find out what has actually happened and I will have to wait for that report this morning and she will want to answer the questions that are put to her. We will have to make decisions."

Immigration officials launched an investigation on Thursday after it was revealed Lady Scotland employed an illegal migrant Tongan Loloahi Tapui.

The Government's top law officer sacked her housekeeper after it emerged that the 27-year-old was in the UK illegally.

It has been reported she has been living in Britain illegally for five years after overstaying a student visa.

Baroness Scotland, who has denied knowing Tapui did not have the right to work here, could face a civil penalty of up to £10,000, according to reports.

She has insisted that she believed that Tapui was entitled to work in Britain and said she had never knowingly employed an illegal immigrant.

The Daily Mail reported that Ms Tapui had been looking after the Attorney General's family home in west London for the past six months.
