Women and girls across the UK face "relentless" harassment on the street and not enough is being done to stop it, MPs say.

The politicians making up the Women and Equalities Committee looked into the issue for nine months and found the amount of harassment meant it became "normalised" for girls growing up.

The MPs are now calling for the government to take action to tackle it.

The Home Office said the issue was a "key priority".

The committee heard evidence that street harassment was widespread, from being shouted at and cat-called through to sexual assaults.

They also heard it took place in a number of public spaces - on transport, in bars and clubs, through online spaces, at universities, in parks and on the street.

'They call my 12-year-old a slut'

One woman, Sarah, told the BBC her 12-year-old daughter has faced harassment on her school bus - including boys pushing her off her seat, spitting at her, and calling her a slut.

Although the school did take action when Sarah reported the incidents, she said more needed to be done to stop such behaviour being normalised.

"It starts off as a bit of banter between young boys and girls but quickly can grow into something more concerning," she said.

"It's an indication of how boys think they can treat girls. If they think it's acceptable at that age what will they be like when they are older?"

Committee chairwoman Maria Miller said: "Women feel the onus is put on them to avoid 'risky' situations - all of this keeps women and girls unequal."

The report concluded that social attitudes underpinned sexual harassment, and the normalisation of it contributed to a "wider negative cultural effect on society".

And while the government has pledged to eliminate sexual harassment of women and girls by 2030, the committee said there was "no evidence of any programme to achieve this".

Next steps

The report outlined seven key recommendations to tackle street harassment:

Force train and bus operators to take tougher action against sexual harassment and block the viewing of pornography on public transport

Ban all non-consensual sharing of intimate images

Publish a new "Violence Against Women and Girls" strategy

Create a public campaign to change attitudes

Take an evidence-based approach to addressing the harms of pornography, along the lines of road safety or anti-smoking campaigns

Tougher laws to ensure pub landlords take action on sexual harassment - and make local authorities consult women's groups before licensing strip clubs

Make it a legal obligation for universities to have policies outlawing sexual harassment

Hollaback! - an international movement tackling harassment - says there is no right or wrong way to respond.

It says the most important thing is to get yourself out of the situation if you feel unsafe.

But if you choose to speak directly to the assailant, it offers the following advice:

Be firm: Look them in the eye and denounce their behaviour with a strong, clear voice Say what feels natural: The important thing is that you are not apologetic in your response Don't engage: Harassers may try to argue with you or dismiss you through further conversation or by making fun of you. As tempting as it may be get into a verbal war with them, it is not recommended. The attention may feed their abusive behaviour Keep moving: Once you've said your piece, keep moving. Harassers do not deserve the pleasure of your company

The Home Office said it had pledged £100m in funding until 2020 to help local services combat violence against women and girls.

And it said it was working on an updated "Violence Against Women and Girls" strategy.

A Home Office spokeswoman said: "Unwelcome advances that intimidate, degrade or humiliate women and girls are an abuse of power and unlawful. Whether in the home, the workplace or in public, sexual harassment is unacceptable.

"The government has made protecting women and girls from all forms of violence, and supporting victims and survivors a key priority."

She said the Home Office would consider the report's recommendations before publishing a full response.

Reality Check: What is the law on harassment?

There's no specific law against sexual harassment in public in the UK - but there are laws prohibiting lots of behaviour that might be considered harassment.

The Protection from Harassment Act 1997 makes it an offence to cause "alarm or distress" or put people "in fear of violence".

There are also laws against stalking.

If street harassment crosses the line into unwanted touching, that can then be dealt with as a sexual offence such as sexual assault.

And when it comes to watching pornography on public transport, there is a pre-internet era law criminalising the public display of "indecent matter" - but the parliamentary inquiry described this as "little-known and likely to be little-used".
