Regional media firm Archant has announced a change in its structure to help focus on delivering growth.

Archant Regional, the group's newspaper publishing arm, will see three of its businesses covering Norfolk, Suffolk, Hertfordshire and Cambridgeshire brought together under a single division, Archant Anglia.

This will be led by Johnny Hustler, currently managing director of magazine business Archant Lifestyle.

Archant said the group's London newspaper and magazine businesses will be combined into a single Archant London entity headed by Enzo Testa, currently leader of the London newspaper business.

Archant Specialist, which spans Archant Life, Archant Specialist and Archant Dialogue, will now also include Archant South West and Archant KOS Media.

Mr Hustler, who previously worked on Archant's Norfolk titles in the 1990s, said: 'The new Anglia structure allows us to orchestrate some of the strongest local media brands in the country and allows us to provide our customers with an array of flexible solutions, whether they are local or stretch across the whole of East Anglia.

Adrian Jeakings, chief executive, Archant said: 'We are living through a time of unprecedented change and increasing competition in the media industry. Our future growth depends on our ability to respond rapidly and cost-effectively to our customers' evolving needs. These structural changes will help us do this better and faster.'

Mr Hustler has lived in the county for almost 50 years and is a former pupil of Norwich School, of which he is a governor.

In the same announcement, Archant said Stephan Phillips, managing director of Archant Norfolk, had decided to take early retirement and Stuart McCreery, managing director of Archant Suffolk, Herts and Cambs had decided to leave Archant to pursue other business interests.

The combined London business will be headed by Enzo Testa, currently leader of the London newspaper business.

He said: 'We believe we are the largest purely local community media player in print in London, and have one of the fastest growing local news websites in London24.com.'

'Combining the strength of our newspapers, magazines and websites across London's communities will increase our ability to grow our presence in the most dynamic media marketplace in the UK, and provide better solutions for our customers.'

Miller Hogg, currently managing director of Archant Specialist, will take over from Mr Hustler at the head of Archant Lifestyle.

Mr Hogg started his publishing career in regional newspapers.

He said: 'We have the biggest county magazine portfolio in the country, alongside a range of quality specialist magazines and a strong and innovative contract publishing business, which I am delighted to be taking forward. I am also looking forward to developing the established newspapers, magazines and digital brands from Kent and the South West.'

Archant group employs about 1,850 people in England and recorded a turnover of �139m in 2010.
