Matrix Chambers and Atkins Thomson Solicitors have been instructed to represent the latest senior UK politician to bring a legal claim against News International in the phone-hacking saga.

Atkins media partner Mark Thomson and Matrix Chambers' Hugh Tomlinson QC are representing deputy Liberal Democrat leader Simon Hughes, who brought the case against News Group Newspapers and former News of the World private investigator Glenn Mulcaire in the High Court earlier this week (9 August).

Thomson and Tomlinson have both taken a number of other roles related to the phone-hacking scandal, including advising Sienna Miller on her claim against News of The World which saw her awarded £100,000 in May this year.

Thomson joined Atkins in June 2009 from Carter-Ruck, which saw the media and privacy law boutique rebrand as Atkins Thomson.

Hughes (pictured), the MP for Bermondsey and Old Southwark, was previously reported to have sought legal advice about a possible lawsuit after allegations emerged that his voicemail had been hacked into by Mulcaire.

Several other senior politicians have launched legal claims in the wake of the hacking scandal, including former Deputy Prime Minster John Prescott, who claimed on the BBC's Andrew Marr show that his phone had been tapped.
