An interactive map will expose the worst spots for harassment in the UK as part of a wider national campaign to help people speak out against sexual violence and harassment.

The Google Maps-style software is the work of the Women's Equality Party, along with digital marketing firm Cheil London and browsing app Blippar.

The campaign, #WECount, began in London and is now being rolled out to the rest of the UK following its success.

The digital map, along with an accompanying social media blitz, will allow users to mark their experiences with Google Maps-style pins, displaying the results online and on a digital billboard in the capital.

Through Blippar's image recognition and augmented reality technology, 10 icons placed around the capital will show the Google Maps pins transformed into an exclamation mark that people can 'blipp' to receive content and information about the campaign and incidents in the area, including available support and victims' stories.

Sophie Walker, Women's Equality Party leader and London Mayoral candidate, said: "An estimated 400,000 sexual offences against women occur in the UK each year. Despite their frequency, the majority of these often violent incidents are unreported, and women are left feeling unsafe and unable to walk without fear on their own streets.
