Brewer Anheuser-Busch InBev has sweetened the terms of its $100 billion-plus takeover offer for SABMiller after a fall in sterling since Britain's vote to leave the European Union and a rise in AB InBev's shares reduced the attractiveness of the original terms for SABMiller shareholders.

AB InBev will now offer £45 a share, an increase from the £44 announced in November last year.
