We hear from a headteacher who has evacuated south-west France following wildfires sweeping across southern Europe. We speak live to John Bolton, National Security Adviser during President Trump's first term, as President Trump threatens 'massive attack'. And we hear from John Wilson, Artistic Director and conductor of the London Sinfonia, ahead of his return to the BBC Proms this evening.
