AFAIK F & L haven't made any pressure for the Portuguese authorities to reject JC's wish to move into our country.

JC (still) has a few influent friends in Portugal.
One of them is Francisco Pinto Balsemão, one of the founders of the Social-Democrat Party (in office these days), the only living one of the 3 founders and holder of card #1 of the party.
Balsemão was Prime-Minister in 1981-83 and later retired from active politics although he maintains some influence in the party.
He reassumed his long-time love with the media.
He owns Portugal's most respected weekly newspaper Expresso and TV Channel SIC.

JC is a long time friend with the Espírito Santo family, but the head of the family fell into disgrace and is being charged for criminal offenses as head of the family bank.
But there are other branches of the family.

Another powerful family friend is Vasco Pereira Coutinho.
JC granted him the title of 1st Marquesss of Pereira Coutinho - Royal Decree 502/2011 of April, 7 - recognizing his descendance from the House of Soidos and his prestige.
(I was in school with the Pereira Coutinho brothers, the youngest one was my class mate )
I am not sure how are the relations between JC and Vasco Pereira Coutinho.
It is well known that at the time of Letizia escapades to Portugal, she stayed at the Pereira Coutinho's castle residence in the Algarve.
Not sure where his loyalty lies these days. Probably with father and son ...
