Robert Henry Halfon is a British Conservative Party politician, the Member of Parliament (MP) for Harlow since 2010.

In the United Kingdom, the minister without portfolio is often a cabinet position, and is sometimes used to enable the chairman of the governing party, contemporarily either the chairman of the Conservative Party or the chair of the Labour Party to attend cabinet meetings. The sinecure positions of Lord Privy Seal, Paymaster General, and Chancellor of the Duchy of Lancaster which have few responsibilities and have a higher rank in the order of precedence than minister without portfolio can also be used to similar effect. The office is currently held by Richard Holden.
