Question: Who is the leader of the largest party in Wallonia? Passage 1:Following the Belgian general election held on 13 June 2010, a process of cabinet formation started in Belgium. The election produced a very fragmented political landscape, with 11 parties elected to the Chamber of Representatives, none of which won more than 20% of the seats. The Flemish-Nationalist New Flemish Alliance (N-VA), the largest party in Flanders and the country as a whole, controlled 27 of 150 seats in the lower chamber. The Francophone Socialist Party (PS), the largest in Wallonia, controlled 26 seats. Cabinet negotiations continued for a long time. On 1 June 2011, Belgium matched the record for time taken to form a new democratic government after an election, at 353 days, held until then by Cambodia in 20032004. On 11 October 2011, the final agreement for institutional reform was presented to the media. A government coalition was named on 5 December 2011 and sworn in after a total of 541 days of negotiations and formation on 6 December 2011, and 589 days without an elected government with Elio Di Rupo named Prime Minister of the Di Rupo I Government.
Passage 2:In 1979, Mann wrote a 180-page draft of Heat. He re-wrote it after making Thief in 1981 hoping to find a director to make it and mentioning it publicly in a promotional interview for his 1983 film The Keep. In the late 1980s, he offered the film to his friend, film director Walter Hill, who turned him down. Following the success of Miami Vice and Crime Story, Mann was to produce a new crime television show for NBC. He turned the script that would become Heat into a 90-minute pilot for a television series featuring the Los Angeles Police Department RobberyHomicide division, featuring Scott Plank in the role of Hanna and Alex McArthur playing the character of Neil McCauley, renamed to Patrick McLaren. The pilot was shot in only nineteen days, atypical for Mann. The script was abridged down to almost a third of its original length, omitting many subplots that made it into Heat. The network was unhappy with Plank as the lead actor, and asked Mann to recast Hanna's role. Mann declined and the show was canceled and the pilot aired on August 27, 1989 as a television film entitled L.A. Takedown. which was later released on VHS and DVD in Europe.
Passage 3:During the Battle of Midway, on 5 June, lookouts aboard Kumano spotted the surfaced USN submarine , and Kumano signaled a 45-degree simultaneous turn to avoid possible torpedoes. Kumano and Suzuya correctly made the turn, but the third vessel in line, Mikuma, made a 90-degree turn by mistake. The error resulted in a collision in which Mikuma was rammed by Mogami. Kumano returned to Kure on 23 June. On 17 July, Kumano and Suzuya were assigned to provide support for the Japanese invasion of Burma, and evaded six torpedoes fired by the Royal Dutch Navy submarine west of Perak, Malaya on 29 July. In August, Kumano and Suzuya were reassigned to support the reinforcement of Guadalcanal. During the Battle of the Eastern Solomons on 24 August, Kumano escaped without seeing combat and returned safely to Truk. However, she was attacked on 14 September north of the Solomon Islands by a flight of ten USAAF B-17 Flying Fortress bombers, and suffered light damage. During the Battle of Santa Cruz on 26 October, she provided support for Admiral Nagumo's Carrier Strike Force, but did not see any combat. She returned to Kure on 7 November and after minor repairs, returned to Rabaul on 4 December with a cargo of troops and supplies. The cruiser continued to remain in the area on patrols and on fast transport missions through the middle of February 1943.
