Puigdemont was officially deposed by Madrid as president of the Calatan region on Friday after its parliament unilaterally declared independence from Spain, and now faces possible criminal charges of rebellion.
Belgian Immigration Minister Theo Francken, a member of the Flemish separatist N-VA party, questioned whether Puigdemont could be sure of a fair trial and said he could be given asylum in Belgium if he asked for it.
"It's not unrealistic (that Belgium could protect Puigdemont), looking at the current situation," Francken told Flemish-language broadcaster VTM yesterday.
So far there has been no indication that Puidgemont will seek to leave Catalonia, and today his deputy insisted he "is and will remain" the president of the regional government.

The unprecedented Catalan crisis was triggered by a banned independence referendum on October 1 that was shunned by many, and marred by police violence, after which the regional parliament voted on Friday to declare independence from Spain.
Madrid dissolved the regional government in response and called an election to replace them, while the international community has spurned the independence declaration and united behind Spanish Prime Minister Mariano Rajoy.
