The firm at the centre of a row over women being made to wear high heels at work has said it has now changed its policy.
Receptionist Nicola Thorp set up a petition calling for it to be made illegal for companies to require female staff to wear high heels at work.
The 27-year-old temp turned up at accountancy firm PwC in flat shoes only to be told by the company dress code was a two to four inch heel.
When she refused, and pointed out that her male colleagues were not required to do the same, she was laughed at and told to go home without pay, she said.
Outsourcing firm Portico said Ms Thorp had "signed the appearance guidelines", but pledged to review them in light of the incident
Managing Director Simon Pratt said the firm had "historically recommended plain court shoes for our female colleagues", but added they "generally allowed plain flat shoes when requested".
He later added the firm has changed its policy allowing women to wear flat shoes depending on their preference.
In a statement, he said: "We are totally committed to being an inclusive and equal opportunities employer, actively embracing diversity and inclusion within all our policies and procedures.
"We are therefore making it very clear that with immediate effect, all our female colleagues can wear plain flat shoes or plain court shoes as they prefer."
