Theresa May will today attempt to relaunch the Tory election campaign amid fears Labour could be about to take the lead in opinion polls.

The Prime Minister will return to the campaign trail with a promise to protect the child victims of domestic violence before she takes part in her first major television showdown with Jeremy Corbyn.

Recent opinion polls have shown the Tory lead over Labour slipping to as little as five points, with party chiefs privately voicing concern they may even be overtaken.

Theresa May will today attempt to relaunch the Tory election campaign amid fears Labour could be about to take the lead in opinion polls

Last night a Tory source told the Daily Mail: ‘We fully expect to fall behind Labour in a poll in the coming days. It will happen.’

In south-west London this afternoon Mrs May will unveil proposals to appoint a domestic violence commissioner to stand up for victims and hold the police and criminal justice system to account.

Longer sentences will also be introduced for offenders found to have harmed children.

The Prime Minister will say: ‘We will launch a relentless drive to help survivors find justice and increase the number of successful prosecutions.’

The Tories yesterday played down claims there have been rows among Mrs May’s top team over plans in the manifesto to reform social care.

Last Monday, after days of controversy, she adapted the proposals to include a cap on the costs individuals could face in their lifetime.

Defence Secretary Sir Michael Fallon yesterday dismissed as ‘Westminster tittle tattle’ reports that Mrs May’s two chiefs-of-staff, Fiona Hill and Nick Timothy, had been divided on the manifesto

Defence Secretary Sir Michael Fallon yesterday dismissed as ‘Westminster tittle tattle’ reports that Mrs May’s two chiefs-of-staff, Fiona Hill and Nick Timothy, had been divided on the manifesto.

He told ITV’s Peston On Sunday: ‘No, this is Theresa May leading our party. We’ve put into the policy now some additional reassurance because of the scaremongering of Labour, further reassurance that people will not lose their home, they will not lose all of their savings.

'But yes, some people will be asked to make a contribution to raising the quality of social care.’

Home Secretary Amber Rudd told the BBC’s Andrew Marr Show: ‘The Prime Minister has said yes, there will be a cap. We will have a green paper to make sure that we set it at the right level and we consider all the other alternatives.’

STURGEON TO HELP CORBYN Nicola Sturgeon last night vowed to help Jeremy Corbyn into power – despite admitting he would not be ‘credible’ as prime minister. The Scottish First Minister said the SNP would look to prop up the Labour leader in a ‘progressive alliance’ if the general election results in a hung parliament. Miss Sturgeon confessed she did not think Mr Corbyn was ‘credible as an alternative prime minister’. But during a BBC One interview with Andrew Neil, the SNP leader said: ‘We would look to be part of a progressive alliance that pursued progressive policies’. Tory party chairman Sir Patrick McLoughlin said last night: ‘This would mean Jeremy Corbyn propped up by a weak and unstable coalition just days before the Brexit negotiations start.’ The SNP won 56 of the 59 Scottish constituencies in 2015, but it is expected to lose seats to the Tories because of opposition to its plans for a second independence referendum.

An Opinium poll for The Observer found the Tory advantage had fallen from 13 points to ten over the past week, with Mrs May’s party on 45 per cent (down one) and Labour 35 per cent (up two).

A ComRes survey for the Sunday Mirror and Independent showed the gap narrowing from 18 points to 12 over the past fortnight, with the Tories on 46 per cent (down two) and Labour 34 per cent (up four).
