THERESA May has rubbished Jeremy Corbyn’s leaked plans for government, saying they would take Britain “back to the past”.

The Prime Minister denounced the leaking of Labour’s draft manifesto as “pretty shambolic," saying it showed the "chaos" that would be unleashed if the party won power.

The 43-page document sets out plans to nationalise key industries, strengthen trade union rights and put extra cash into the NHS in England by increasing taxes on top earners.

Mrs May seized on the divisions in Labour, that led to the leak; some have suggested it was an act of sabotage from within the party's HQ.

“What we see from the issue around the Labour Party's manifesto is, first of all, it is pretty shambolic the way the manifesto has come out,” she told Channel Four News.

"That shows the sort of chaos that we would see from a Labour government. But, crucially, if you look at what they are suggesting, if you take their manifesto overall, actually, what they are suggesting is taking us back to the past.

"What I'm interested in is dealing with the challenges that we face today but making a better future for this country."

The PM made the comments during a visit to the Young Minds charity in central London where she chatted to staff on the parental helpline set up to help mothers and fathers with concerns about their children's mental health.

Meantime, Mrs May will face an online grilling on Monday with questions streaming in over the internet.

The PM, who has refused to take part in TV debates during the General Election campaign, will spend around 45 minutes taking part in the Facebook Live session with Robert Peston, ITV News's political editor.

Other leaders are set to follow Mrs May in taking part in one of the sessions, which will see questions submitted by the online audience.

Mr Corbyn, Nicola Sturgeon, the SNP leader, Tim Farron for the Liberal Democrats, Paul Nuttall for Ukip, Leanne Wood for Plaid Cymru and Green Party co-leader Caroline Lucas have all been invited to take part in the run-up to polling day.
