Mr O'Flynn, speaking at a policy launch in Westminster, said: "We could I think be forgiven for finding it galling that the ever-pragmatic Tory party has lately donned so many of our clothes - and isn't it interesting, by the way, that Mrs May is being ferried around the country in the very battlebus that was used for the Conservative Remain campaign this time previous year?"
Tories will outline new protections for gig economy workers.
In her biggest raid into Labour's territory, the Prime Minister will announce the Conservative manifesto will include a wide range of social policies such as the right to request leave for training, the right to child bereavement leave, up to 52 weeks off for workers who are caring for family members, and possible criminal charges for bosses that break pensions rules. If the Conservatives were serious about supporting carers they would acknowledge that the United Kingdom social security system is one of the least secure in Western Europe and would take on board the recent recommendations of the UN Human Rights Council.

Tim Goodwin, an associate at the law firm Winckworth Sherwood, said: "It was David Cameron who scaled back employment rights radically, most notably making it harder to bring unfair dismissal claims and introducing huge tribunal fees - in most cases up to £1,200 - which has seen claims fall by up to 70%". May is attempting to rebrand the Tories as the party for workers.
"Our plans will be the greatest expansion in workers' rights by any Conservative government in history".
Taking a swipe at Margaret Thatcher's tracks record, she said: "Time and again the Tories have let down working people and have cut workers rights".
"However, it should be noted that while the Conservative Party has what appears to be an unassailable lead, other parties can still narrow the gap as more than one in 10 (12 percent) of "likely voters" in the election are still undecided".
"With the limited powers of the Scottish Parliament, the SNP government has worked tirelessly to support workers".
