In the 2015 general election, he was elected with 59 per cent of the vote and a majority of 18,461. 
Dowden studied law at Cambridge. In 2004 he joined the Conservative Research Department. He left the Tories in 2007 to work for the PR and lobbying company Hill & Knowlton but returned to the party to work alongside Andy Coulson in early 2009.
During his time in Cameron's team, Dowden has been described as one of the most highly regarded figures in Downing Street, 'with an expertise in the attacking form of political communications that has led to comparisons with Alastair Campbell', former spindoctor to Labour Prime Minister Tony Blair. His previous roles include working to link Number 10 with the Conservative Campaign Headquarters (CCHQ), he was replaced in this role by Adam Atashzai, who had worked on the Treasury brief at CCHQ. 
Dowden has broad experience in domestic policy reform, immigration, welfare, health and criminal justice. 
Dowden left his role as Special Advisor to the Prime Minister (Cabinet Office) in October 2014.
In December 2014, after leaving Downing Street, Mr Dowden took on a Consultant role at Policy Exchange, in which he would advise on a public education project regarding the role free markets play within a free society. Despite occasionally attending seminars whilst in office, ACOBA found no conflict of interest here, and approved the appointment.
In July of 2015, he also sought the advice of ACOBA on an appointment to Political Advisor for the Association of Independent Professionals and the Self Employed (IPSE), a non-profit that represents freelance and self employed individuals. The Committee approved this position as it was made clear that the former Special Adviser's new role would not in any way be involved with his former department, central government, lobbying or parliamentary representation.
In the same month, he was permitted to take on a post as Political Advisor to Caxton Europe Asset Management, a trading and investment firm, on the grounds that he would not be affecting policy and had not effected the organisation during his service to the crown. 
In October 2015, Dowden signed a letter in The Guardian along with more than 150 people drawn from the arts and politics. The letter launched Culture for Coexistence, an organisation that opposes the Boycott, Divestment and Sanctions movement.
