British-born Penelope Kathryn Fillon, the extremely publicity-averse wife of presidential favourite François Fillon, is now at the centre of a scandal in France, dubbed "PenelopeGate". Here's what you need to know about her.
Until this week's scandal, in which it is alleged she was paid half a million euros by her husband to act as his parliamentary assistant, Penelope Fillon has pretty much stayed out of the glare of the public eye in France.
"Up until now, I have never been involved in the political life of my husband", she said in October 2016, which perhaps, given the accusations that she was indeed actually working for him, now seems a bizarre statement.
But before "Penelope Gate" kicked off in France, everything was a little different.
She's "ultra-discreet", Le Figaro newspaper has written in the past, and Le Parisien called her la femme de l'ombre ("the woman of the shadows"). Closer magazine even called her the "anti-Carla Bruni" late last year, in a reference to ex-president Nicolas Sarkozy's publicity hungry wife.
They were all talking about Penelope Kathryn Fillon, the 60-year-old Welshwoman who is married to François Fillon, the man who polls say is the likely winner of this year's election. Although what do polls mean these days?
Fillon's surprise victory in last November's centre-right primary prompted a host of articles about his partner as the media eyed up the country's possible next first lady.
Given her desire for a "life in the shadows" it's a fair assumption that the thought of her becoming France's first ever Welsh first lady probably terrifies her. As will the developing scandal about whether she actually did anything to earn the half a million euros, paid to her for being her husband's assistant.
When Fillon became Prime Minister in 2007, she had this to say: "People are asking me what my new role is, but there isn't one.
"At the end of this week everything will calm down and I can go back to normal. People do not recognize me on the streets and I don't want to be. I would be terrified," she said, before admitting to walking on the other side of the street to her husband sometimes.
But there are at least signs she is willing to embrace the spotlight a little.
She has even taken up a lead role by helping the group "Women with Fillon" (Les Femmes avec Fillon).
But how did a woman from the Welsh countryside end up the likely next first lady in France?
Born Penelope Clarke, she studied to be a lawyer in Wales before heading to France for a gap year in the late seventies where she met the man who was to become her husband.
"It wasn't a particularly heart-stopping moment," she later said
in recalling her first meeting with Francois Fillon.
However, the pair fell in love and thanks to Fillon's regular and determined trips across the Channel to woo her, and she eventually moved to France, like many expats, on a one-way ticket.
And the ties between the Clarkes and the Fillons were to grow even tighter with Penelope's sister wedding Fillon's younger brother Philippe a few years later.
On French soil the Welsh woman never ditched her reserved and country-girl approach to life. She never worked as a lawyer and instead dedicated her life to raising their five children.
She has spent much of her time in France at the family home in Solesmes, north western France, where the couple own a chateau.
In 2014 she was elected a municipal councillor in the town, a position that her husband once held.
The fiercely private woman has rarely granted interviews, which is perhaps not surprising given the fact that the last time the Fillons let the press into their home they ended up getting mocked by the public.
The Paris Match magazine ran a full page spread with a picture of the entire family in front of their countryside chateau with the caption: "To govern well, you need balance".
A columnist at Nouvel Obs
wrote that the spread was like a guide in "how to ruin your image".
"Is there anyone actually steering Francois Fillon's communication team," the paper asked, noting that by parading his wealth he was "cutting himself off from a huge majority of France's population."
Fillon told the French media afterwards that he had no intentions of hiding who he really was.
"I am not like some people who own a villa on the Riviera but who never lets it be seen," he said.
And - in good news for Anglophones the world over - she has said in the past that her husband speaks English "very well", though the family doesn't often speak it at home.
If Fillon does win next year's presidential election some British expats in France have suggested it could be good for them because "Penelope will look out for her own."
It might be worth preparing your letters asking her to help you get a permanent residency permit ready for when Brexit eventually happens.
"I've spent 35 years in the shadows, but now the challenge is different," she told Le Figaro in an interview published late last year.
"Now Francois is running for president of the Republic."
And it could just be that we get France's first Welsh woman by the president's side.
