Klippan Paper chairman Jan Bernander has bought a further 750,000 shares in Inveresk in an individual capacity, taking his total stake to 6.3%.
Bernanders total investment in Inveresk now amounts to 3.2m shares after his purchase last month (PrintWeek, 26 January).
"He obviously views our shares as an exceptionally good buy and seems to be re-aligning his portfolio," said Inveresk group finance director Gerard Cassels.
The deal was announced in a letter to the company announcements office, advising that Bernander had a material notifiable interest of 6.3% of the companys issued ordinary share capital.
Inveresks shares are trading at 12.5p, but have been as low as 8.5p in the past year.
"We have always said that we would listen to any co-operation that Klippan may offer, but this has to be done with the full co-operation of the shareholders and not just one individual," said Cassels.
"We would be delighted to speak to Mr Bernander at anytime, but he appears to be more keen to speak to the press than us."
Klippan Paper acquired 3.8m shares in Inveresk last year. It indicated a "desire for an improvement in its shareholding" and was "looking for board representation".
Inveresks next shareholders meeting is scheduled for the end of April, which Bernander as a shareholder is entitled to attend.
