5x15 SOLD OUT

The highlight of this edition of 5x15 – during which five speakers each talk for 15 minutes – is surely Joanna Lumley, who will be discussed the Garden Bridge, planned to stretch its leafy loveliness from Temple across the Thames to the South Bank. But the other guests are no slouches, including Simon Jenkins from the National Trust on England's 100 best views and the decidedly provocative Vicky Pryce on 'Prisonomics'.
