Real Madrid's plans to renovate the Santiago Bernabeu have been suspended by the Spanish High Court amid an investigation by the European Commission into alleged corruption.
Madrid unveiled their proposals for the spectacular stadium in January, with the all-new Bernabeu to include a shopping centre complex and a hotel in an area to cover 12,250 metres adjacent to the ground - almost half of which is currently unoccupied land and would be given to the club as part of the agreement.
In order to approve those plans, Madrid's government approved changes to the city's General Urbanisation Plan from 2011.
However, the European Commission has opened an investigation into possible "illegal public assistance" by part of the government towards the club.
A group of ecologists have also filed an official complaint claiming that Madrid reneged on a previous agreement to build an underground car park and a walkway giving access to the stadium in 1991.
"The club never fulfilled its part and ended up owing the government €2.8 million," a statement from the action group Ecologistas en Accion AEDENAT read.
The Spanish High Court have decided that the European investigation means there are sufficient grounds to bring a halt to the €400m project.
Madrid have 10 days to lodge an official appeal against the decision.
