The number of Members needs to be increased because the last European Parliament elections were held under the rules of the Nice Treaty, which sets the number of MEPs at 736, while the new Lisbon Treaty, which entered into force on 1st December 2009, provides for 751 seats.
Deputātu skaits ir jāpalielina, jo iepriekšējās Parlamenta vēlēšanas notika, kad spēkā vēl bija Nicas līgums.
