Among the witnesses due to be questioned over the next three days is British ex-pat Robert Murat.
Mr Murat, who is not a suspect, was first questioned when three-year-old Madeleine went missing from the Algarve resort of Praia da Luz seven years ago.
He was cleared of any wrongdoing and won substantial damages from British newspapers over how he was portrayed at the time.
The BBC has learnt that of 10 people of interest that British police have requested be interviewed by Portuguese police in Faro, three are being questioned on Tuesday, four on Wednesday - including Mr Murat - and three on Thursday.
The 11th person is a woman who is currently in the UK and will be questioned there at a later date.
Some of the interviewees are former employees of the Ocean Club where the McCanns were staying when Madeleine went missing, BBC correspondent Christian Fraser said.
A convicted rapist was interviewed for the third time yesterday over the disappearance of Madeleine McCann.
Scotland Yard detectives spent more than six hours talking to dreadlocked pig farmer
Joaquim Jose Marques.
Marques is among 11 men and women who this week are being interviewed by British and Portuguese officers probing the mystery.
The interviews are the *latest stage in the Yard’s multi-million pound Operation Grange, and will mark the start of a major week for Madeleine’s parents Kate and Gerry McCann.
In a Lisbon court tomorrow, lawyers are expected to make their final speeches in a £1million libel action brought by the McCanns against former police chief Goncalo Amaral over claims he made in his 2008 book The Truth Of The Lie.
He headed the investigation into Madeleine’s disappearance from a holiday apartment in Praia da Luz in the Algarve in 2007.
Allegations in the book led Mrs McCann to contemplate suicide as she struggled to cope with what she called the ex-police officer’s “smear campaign”.
.....this is actually taking place today, and I can find no other references to it anywhere else in the media (via a google search).
*Miguel Coroadinha*, representing TVI, started his allegations with a copy of today's Correio da Manha and an article about the Faro questioning sessions, using it to make the following points:
* the visits by SY deviate attention from the trial, repeatedly and conveniently
The next session takes place on the 21st of January 2015.
It will serve the purpose of the judge reading out what has been established as "matéria de facto" by the court......

* Isabel Duarte (lawyer for the McCanns)* was busy today, presumably another trial.
She tried to get the session postponed but did not succeed.
She missed her chance but will be allowed to present written allegations after the 30-day suspension runs out.*
She oversaw the investigation into the murder of Tia Sharp, whose body was found in the loft of her grandmother's house in New Addington, south London
Kate and Gerry McCann will leave gifts in her pink bedroom, as they have every year since she vanished aged three during a family holiday to the Algarve in 2007.
During a private hearing yesterday, Judge Maria Emilia Melo e Castro ruled in favour of the McCanns by acknowledging the hurt the book had caused them.
No date has yet been set for a full judgment but the McCanns, from Rothley, Leicestershire, hope it will be next month.

And only a few days ago, Detective Chief Inspector Nicola Wall — the newly installed head of Operation Grange — flew to Lisbon with a small team of officers for a private meeting with the authorities.
Each such development raises fresh hopes and excites the media, but so far they have all come to nothing. And one had to ask whether DCI Andy Redwood, who had set up the inquiry and had overseen it enthusiastically for four years, would have recently stood down had he been on the brink of solving the biggest case of his career.
All of which goes to explain why the chairman of the Metropolitan Police Federation has now suggested that it might be time to pull the plug on Operation Grange.
The sad truth is, however, that when we examine such exceptional cases, they do little to support the argument for a hugely expensive and protracted police investigation.
Jaycee’s deranged kidnapper, Phillip Craig Garrido, virtually shopped himself to the FBI by presenting them with a rambling essay purporting to offer a cure for sexual predators, and later parading her and another of his victims at a university campus lecture.
The salvation of Zephany, whose mother Celeste has urged the McCanns to continue praying as she did, and ‘never give up’, owed still more to happenstance. Her identity was discovered after she was unwittingly enrolled at the same school as her sister, and fellow pupils noticed their extraordinarily similar looks.
So how much time and money might you expect the police to invest in searching for one ‘medium risk’ child? According to a recent study by Portsmouth University’s Centre For Missing Persons, the amount is astonishingly low: between £1,325 and £2,415.
Compared with the millions poured into the search for Madeleine, this figure — which covers such basic procedures as taking an initial call, risk assessment, obtaining a photograph of the child, undertaking a house search, and a police national computer check — is derisory indeed.
