From 1973 to 1989 he served five terms in the
National Assembly. He was Minister Delegate for Housing from 1989 to 1990 and then Minister of Public Works, Housing, Transport, and Maritime Affairs from December 1990 to May 1991 in
Michel Rocard's government. He then served as Secretary of State for Housing under
Lionel Jospin from 1997 to 2001. His (right to housing) law in May 1990 was something of a landmark, in that it enforced the basic right to housing, by establishing access to housing as a legal principle. It was known as , Besson's law. The opening two sentences of the legislation set the parameters: "Guaranteeing the right to housing is a duty of solidarity for the entire nation. Anyone experiencing particular difficulties, notably due to inadequate resources or living conditions, is entitled to assistance from the community, under the conditions set forth in this law, to access and maintain decent and independent housing." He supported local housing integration initiatives during his time in office. Besson championed
traveller rights, notably through the
Besson 2 law, implemented in July 2000, which requires municipalities over 5,000 residents to provide designated traveller sites. This reinforced the 1990 legislation to set a target of 30,000 additional plots for travellers over five years. This was not a particularly popular initiative, but as minister he had visited a traveller site to pay condolences to a family that had lost a child through drowning, and that had an impact on his approach to the issue. He was a joint author of the
Solidarity and Urban Renewal (SRU) law of December 2000, whose Article 55 obliges larger municipalities to meet social housing targets. Municipalities over 3,500 residents would need to ensure at least 20% of housing development fell into the category of
social housing. This legislation was credited by the law's supporters with enabling one million social housing units, around half of the total residential building programme in France, over the last 25 years, and it still remains part of French housing policy. == Other campaigns ==
