After the election he declared that he was uninterested in partisan politics and refused the idea of turning his supporting movement into a party. He was deserted by some of his previous supporters after accepting an invite by the centre-right Social Democratic leader Pedro Passos Coelho to be the head of the Social Democratic lists and to run for MP for Lisbon for the elections which would happen in June 2011 after the fall of the Sócrates government. The fact that Nobre, considered a leftist and a Soarist socialist and who had supported the Left Bloc in 2009 (saying he "shared the values of the party"), was heading the electoral lists of a rightwing party. Other supporters were disappointed by the fact that he was involved in a party at all after what he had said about not involving in party politics. Nobre defended himself that he trusted Passos Coelho personally (stating he was an honest man) and that (quoting Gandhi) only who doesn't look for the truth never changes his mind. He also stated that he believed the left-right division was worn out, and remembered that he had supported other rightists like José Manuel Durão Barroso in 2003 and António Capucho for the City Hall of Cascais.

Nobre was elected, despite much discussion over his acceptance of the offer (including his statement that he was running just to be Speaker of the Portuguese Parliament and not an MP) with a quite positive result over Socialist competitor Eduardo Ferro Rodrigues. Despite the apparent support of the Social Democratic seats in the Parliament, on 20 June 2011, in the first meeting of the Parliament elected by the 5 June election, Nobre failed to be elected Speaker even after two round of voting (gaining even fewer votes the second time around). It is argued that his defeat was not only due to opposition in the Social Democrats to having an independent as the highest standing among them in Parliament, to opposition of all parties to a non-partisan in Parliament. After failing to become Speaker of the Assembly, Nobre renounced his seat. He still attended to the parliamentary meeting of 21 June and had two justified absences (due to illness) on the meetings of 30 June and 1 July.^[1]

Since then, he has not had involvement in politics except for some political commentaries in television.
