Deri Watkins has been appointed Mars impulse sales director in the UK, replacing Shaid Shah, who has been promoted to general manager of the business in Ireland.

Watkins will now be in charge of the impulse side of the business, which accounts for about £500m of consumer sales a year.

He was formerly the head of strategy for the UK chocolate business. It has yet to be decided who will take over his former role.

Andrew Clarke, formerly the manager in Ireland, has been appointed manager of the complementary petcare business in Europe.
