Sir Philip Green's lawyers hand-delivered letters to a witness's home in an attempt to "threaten" her to stay silent about sexual harassment allegations made against him, a court has heard.

The Topshop owner has also sent "intimidating" letters to each of his alleged victims warning them against speaking out, the High Court heard.

The billionaire's lawyers sent the letters to those who signed non-disclosure agreements (NDAs) and a witness to warn them that if allegations about him were published he would take legal action against them.

In the case of one witness, a representative for Schillings attended her home after dark on Monday evening to deliver a similar letter, it was said.

Court documents also show that Sir Philip's lawyers said that he did touch employees, but in a "non sexual way".

Other documents made public, submitted by lawyers for this newspaper describe the allegations against the businessman as being "gross and unlawful" and "amounting to criminal offences".
