Dawn Butler has come to the defence of Boris Johnson's neighbours, who called the police after a row broke out at the politician's home.
The pair - identified as Tom Penn and his wife Eve Leigh - have come under fire since reporting the disturbance, with Jacob Rees-Mogg branding them “Corbynista curtain twitchers”.
But Labour MP Ms Butler said it was important to call the police in cases of suspected "domestic abuse".
The shadow women and equalities secretary told talkRADIO’s Matthew Wright: “If you suspect anything with your neighbours - if you hear screaming and shouting - and you think there is any domestic abuse of any kind then you should call the police.
“Two women a week are murdered by a partner or ex-partner.”
Mr Johnson’s neighbours also made an audio recording of the argument between the Tory leadership frontrunner and his partner Carrie Symonds, which they shared with The Guardian on Saturday.
The Metropolitan Police attended Mr Johnson's south London address, but found "there were no offences or concerns apparent to the officers and there was no cause for police action".
A statement, signed by 12 domestic abuse experts, has said that despite no evidence of domestic abuse in this instance, the neighbours had done the right thing.
They wrote: “The weekend has been full of comment about the relationship we have with our neighbours.
“It’s not for us to judge what happens in anyone’s relationship, but it is for us all to take action if we are concerned about someone’s safety.
“Don’t walk on by if you are worried. Ask if they are ok. Tell someone."
Mr Johnson has repeatedly refused to talk about why the police were called to the flat.
