Labour was mocked yesterday for drawing up plans to create thousands of nursery places without being able to say how it would pay for them.
Under proposals expected to be in the party's manifesto, it is looking to fund nurseries in primary schools across the country to provide continuity of education for younger children.
But shadow attorney general Emily Thornberry squirmed yesterday as she was unable to say how the plan, including extra staff needed, would be paid for.
Asked on Good Morning Britain 'how would you pay for it?' and 'where would the money come from?', she dodged the question, saying: 'Well, that's why we're looking... that's why we're having a proper review at the moment.
'But one thing I can say to you is that anything we do announce will be properly funded and we won't be announcing anything the country cannot afford.'
But Tory party chairman Richard Holden hit back, saying: 'We have a comprehensive fully-funded and costed plan that's delivering the biggest ever uplift in childcare support for millions of families across the country.
'In contrast, Sir Keir Starmer is pumping out desperate, uncosted and flimsy ideas with, as ever, no plan to pay for it.
'The British public aren't as daft as the Labour membership and will want more from Sir Keir Starmer than warm words and pie-in-the-sky ideas.
'This comes on top of Sir Keir's botched pledge to spend an extra £28billion a year, leaving a massive black hole in our economy all whilst supposedly 'cutting debt'.
'The the only way Labour's irresponsible spending sums add up is by putting new and higher taxes on everyone.'
