Plans to jail someone for up to two years for catcalling, following someone or blocking their path on the street were approved by MPs today.
Publicly harassing someone on the basis of their sex is set to become a specific crime after a bill received an unopposed third reading in the Commons.
Former Tory minister Greg Clark, who put forward the changes, said it was a "historic day" and "astonishing" that the law does not already contain such an offence.
