BRUSSELS/MADRID, Oct 31 (Reuters) - Catalonias ousted leader Carles Puigdemont said on Tuesday he accepted the snap election called by Spains central government after Madrid took control of the region to block its push for independence.

Puigdemont, speaking at a news conference in Brussels, also said he was not seeking asylum in Belgium after Spains state prosecutor recommended charges for rebellion and sedition be brought against him. He would return to Catalonia when given guarantees by the Spanish government, he said.

Puigdemonts announcement that he would accept the regional election on Dec. 21 confirmed that the Madrid government had gained the upper hand in the protracted struggle over Catalonia, for now at least.

Resistance to Madrids imposition of direct control on Catalonia failed to materialise at the start of the week and the secessionist leadership is in disarray.

Spains Constitutional Court on Tuesday blocked the unilateral declaration of independence made by the regional parliament on Friday, a move that gained no traction and led to its dismissal less than an hour after it was made.

I ask the Catalan people to prepare for a long road. Democracy will be the foundation of our victory, Puigdemont said.

The Spanish government has said Puigdemont was welcome to take his chances and stand in the Dec. 21 election, called by Prime Minister Mariano Rajoy as a way to resolve the stand-off.

The political crisis, Spains gravest in the four decades since the return of democracy in the late 1970s, was triggered by an independence referendum in Catalonia on Oct. 1.

Though it was declared illegal by Spanish courts and less than half Catalonias eligible voters took part, the pro-secessionist regional government said the vote gave it a mandate for independence.

European nations including Britain, Germany and France have backed Rajoy and rejected an independent Catalan state, although some have called for dialogue between the opposing sides.
