Description

1.  Press release dated April 16, 2007  -  On-market share buy back


                                                                   16 April 2007


                    BUNZL ANNOUNCES ON-MARKET SHARE BUY BACK

Bunzl plc, the international distribution and outsourcing Group, today announces
that it intends to resume its on-market share buy back programme. Subject to
market conditions and based on current expectations, it is anticipated that the
Company will spend up to GBP100 million in 2007.

This is consistent with the Board's strategic priority of growing both
organically and by acquisition and its objective of operating with an
appropriate balance sheet structure. While the acquisition pipeline is good, the
Board believes that the Group's high and consistent level of cash generation
allows the Company to operate with a somewhat more leveraged capital structure.
