what duties does the home secretary have to parliament
Home Secretary The Home Secretary is responsible for the internal affairs of England and Wales, and for immigration and citizenship for the United Kingdom. The remit of the Home Office also includes policing in England and Wales and matters of national security, as the Security Service (MI5) is directly accountable to the Home Secretary.[1] Formerly, the Home Secretary was the minister responsible for prisons and probation in England and Wales; however in 2005 those responsibilities were transferred to the newly created Ministry of Justice under the Lord Chancellor.
House of Commons of the United Kingdom Although it does not formally elect the prime minister, the position of the parties in the House of Commons is of overriding importance. By convention, the prime minister is answerable to, and must maintain the support of, the House of Commons. Thus, whenever the office of prime minister falls vacant, the Sovereign appoints the person who has the support of the House, or who is most likely to command the support of the Houseâ€”normally the leader of the largest party in the Commons, while the leader of the second-largest party becomes the Leader of the Opposition. Since 1963, by convention, the prime minister is always a member of the House of Commons, rather than the House of Lords.
