A JPMorgan Cazenove team led by City broking grandee David Mayhew is helping AkzoNobel to communicate more effectively with shareholders, following the Dutch chemicals group’s rebuttal of a takeover approach earlier this year.

AkzoNobel has called an extraordinary general meeting of shareholders for September 8, at which it said it will offer "further explanation and discussion" of its responses to unsolicited takeover approaches from US rival PPG Industries.
