Since winning power, the Labour government has painted a bleak picture of the public finances - but in his speech the PM will seek to present a more positive vision for the future.
"And if the writing on the back of the letter is a reply, then it's also a story about the first ever bit of writing which can be attributed to Anne Hathaway."The letter refers to the boy being a fatherless apprentice and through his research Prof Steggle says there was only one person in London called John Butts who fits that criterion.
The letter also refers to a Trinity Lane and of the four married couples called Shakspaire (spelling of the time) known to be in London in that period, only William and Anne are likely to have lived in that area."It at least doubles the number of letters known to be addressed to or sent from Shakespeare and his family," Prof Steggle said."Currently, there's only one known. It also shows a side of Shakespeare's London life that's not been known before, giving him a new address in Trinity Lane and a whole new sphere of activity for him."
Prof Steggle said it "opens the door" to the idea Shakespeare's wife did indeed spend "significant" time with her husband in London."It's not a complete slam dunk," he told the BBC.
"It's a possibility that seems difficult to avoid, rather than a certainty."
Speaking on BBC Radio 4's World at One programme, author Maggie O'Farrell, whose book Hamnet is a fictionalised account of the marriage between Shakespeare and his wife as they deal with the loss of their son, called the discovery "thrilling" and "wonderful".In its response to the recommendations, the SPS said it had committed to "rapid and systemic change" following the FAI.
"We have accepted all of the recommendations made in Sheriff Collins's determination, in full, and are committed to a range of actions which will be enduring, impactful, and lifesaving," it said."The response includes an overhaul of our suicide prevention policy, Talk To Me, based on the advice of independent experts; additional protective support for young people in custody in their first 72 hours following admission; and work to make the rooms that people live in as safe as possible.
"Some actions have already been completed, while others are under way."The SPS said all bunk beds had been removed from the rooms of young people in HMP & YOI Polmont, as well as rectangular doorstops, to improve safety.
