Ann Widdecombe has called for regular stop and searching to be introduced in a bid to tackle violent crime.
Her comments come after police confirmed the death of a nine-year-old girl following a shooting in Liverpool.
While last week, 87-year-old Thomas O’Halloran was stabbed to death while riding a mobility scooter in Greenford, west London.
Speaking on GB News’ The Briefing with Tom Harwood, Ms Widdecombe said: “On the crime side, as Giuliani did in New York, we should be investing in a vast increase in policing, having zero tolerance.

“And focusing heavily in local areas on what the problem is, in London for example it's knife crime.
“There should be regular stop and searching and you should know that if you leave your house carrying a knife you are likely to be stopped and searched.
“And if you are stopped and searched you won’t just be patted on the head and told to go home, you’ll be arrested.
“If we don’t have that sort of decisive action, you can talk as much all you like, nothing is going to happen.”
While Ms Widdecombe also waded in on the migrant crisis, calling for national identity cards to be introduced.
She continued: “I think there are two things we should do, I think we should introduce national identity cards.
“Now that doesn’t please my libertarian soul but the fact is we’re in an emergency and they go into the illegal economy and the only way we’re going to know who we’ve got, working where, paying or skiving taxes is if we have national identity cards which have to be ridiculed.
“The second thing we need to do is to house all new asylum seekers in secure accommodation so that we know where they are and so they can’t just disappear into the illegal economy.
“And then when we come to say no as we will with the majority of them, we will be able to deport them because we know where they are.
“It also benefits the genuine claimants because they can be dealt with much quicker instead of being stuck in the queue with 100,000 others from whom they’re not distinguishable.”
It comes after a record 1,295 migrants arrived in the UK on Monday after crossing the Channel, according to Government figures.
It is the highest daily total since current records began in 2018.
Some 27 boats made the journey, the provisional Ministry of Defence (MoD) data said, which suggests an average of around 48 people per boat.
The previous highest daily number was 1,185, on November 11, 2021.
