Following his party's defeat in the 2014 general elections, he became Leader of the Opposition for the sixth time, making him the longest ever to serve in this constitutional position.

Geneviève Bérenger, his mother, was the daughter of Auguste Esnouf, an engineer and author who used pen name Savinien Mérédac to write novels and newspaper articles.

In early 1983, Bérenger proposed a constitutional amendment removing the executive powers of the prime minister and entrusting them to the Cabinet collectively.

[18] In 1999, the national opinion polls showed that Prime Minister Navin Ramgoolam's Labour Party was the favorite to win the elections due in 2000.

In an hour-long meeting organized by Bodhoo, Berenger made up his quarrel with Jugnauth and agreed to an electoral alliance and a power-sharing deal, should they win the election.

The power-sharing agreement was briefly in doubt when, in 2001, Bérenger faced a charge of aiding and abetting a murder suspect to escape arrest.

Swaleha Joomun, a widow, was suing the deputy premier for facilitating the escape of Bissessur who was wanted in connection with a triple murder which occurred on 26 October 1996 in Port Louis.

[19][20] Bérenger defended himself by saying that the reason he had helped Bissessur was because the latter wanted to reveal what he knew on the escadron de la mort (death squad).

In January 2013, Berenger announced that he had tonsil cancer in a press conference, and let the population know of his plans for treatment in France and that Alan Ganoo was to lead the MMM during his absence.

Navin Ramgoolam would remain prime minister until a new constitution could be adopted to enhance the powers of the President, before resigning to make place for Bérenger to succeed him.

[24] In 1971 Bérenger narrowly escaped a murder attempt, whilst his assistant Azor Adelaide died soon after being shot by rival political activists on Chasteauneuf Street in Curepipe.

Sheik Hossen made allegations against Special Branch's director Fulena, his deputy Sénèque, officers Jean-Paul Venkatachellum and Jean Ramiah.

The Labour-PMSD-CAM government was alleged to be concerned by Le Mauricien's adoption of the new offset printing technology which would strengthen Bérenger's MMM.

Under cover of parliamentary immunity Bérenger further reiterated the accusations against the intelligence police, which led to a lengthy investigation and court appearances.

Bérenger formed part of the government at the time of the Illovo Deal, and his adviser and broker Jean-Mée Desvaux negotiated with Anerood Jugnauth at the latter's office in order for the elite Franco-Mauritian conglomerate to pocket Rs 6 Billion whilst the State would only receive Rs 3 Billion of the deal involving the sale of more than 10,000 arpents of agricultural land.

Prior to the Desvaux-Jugnauth meeting the Rs 6 Billion worth of land would have been acquired by the State (to be on sold and distributed to interested small planters).

[32][33][34] As Leader of the Opposition Paul Bérenger showed disrespect towards women when he publicly insulted Nita Deerpalsing during a session of the National Assembly in August 2008.

[35] In response to MP Nita Deerpalsing's expression of support for then Attorney General Rama Valayden Bérenger commented rode ene mari pou li marié do!

[38][39] Following an investigation by financier African Development Bank (ADB), Paul Bérenger was named as one of the recipients of bribes via local company PAD & Co. Ltd. on behalf of Danish firm Burmeister & Wain Scandinavian Contractor (BWSC), which won the contract for the major upgrade of ailing St Louis diesel power station.
