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.

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.
