Cabinet Office minister for cyber security and G-Cloud, Francis Maude, has announced plans to step down, arguing that it is time for a younger candidate to lead.
Maude, who currently holds the seat for Horsham in West Sussex, announced his resignation in a letter seen by V3.
"27 years is a long time to serve as a MP, and I believe now is the right time to make way for a younger candidate to carry the Conservative flag," he said.
Maude is a veteran politician who held ministerial positions with Margaret Thatcher, John Major and David Cameron.
He won his seat in the 2010 General Election and was made minister for the Cabinet Office and Paymaster General in May the same year.
Maude was responsible for several technology and privacy remits, including public sector efficiency and reform, industrial relations strategy in the public sector, government transparency and cyber security.
During his time in the role Maude helped to develop the UK government's cyber security and digital strategy.
Key achievements include the launch of the UK's Cyber Security Information Partnership (CSIP) and the creation of the UK Computer Emergency Response Team.
The CISP has been criticised by some industry commentators for failing to help small businesses, but the initiative has been credited as a success and as evidence of the benefits of sharing threat data.
UK prime minister David Cameron and US president Barack Obama announced plans on 16 January to create specialist cooperative "cyber cells" run by the UK and the US to further increase the amount of threat data being shared between the public and private sectors.
More recently, Maude announced the creation of a 'cyber insurance' initiative in November. The collaboration will see 12 major insurers, including Marsh, coordinate in the creation of a comprehensive cyber security insurance model.
Maude highlighted his efforts using IT to improve government efficiency as one of his biggest achievements.
"Since 2010 I have served as the minister for the Cabinet Office, designing and driving a programme which saved taxpayers £14.3bn last year alone," he said.
"We set up the Government Digital Service, now being copied in the US and Australia, which has replaced hundreds of websites with the award-winning Gov.uk, moving services online and cutting the costs of government IT while hugely improving the service."
Maude added that he has put procedures in place to see that the work continues after he leaves.
"I've worked closely with our brilliant chancellor to drive these reforms, but there is much to do - before the election and after - to ensure that the reforms are irreversible," he said.
A Cabinet Office spokesperson told V3 that work on cyber security will continue unhindered until a new MP is elected.
