July 15 has been declared an annual national holiday of "democracy and unity" and the authorities want people to see the foiling of the putsch as a historic victory of Turkish democracy.

Friday's measures, however, mean that 50,000 people have been arrested and a further 100,000 sacked in response to the thwarted bid to overthrow Erdogan.

Some 7,563 people were fired in the latest cull, the state-run Anadolu news agency reported, with nearly 350 retired army members also stripped of their rank. Hurriyet daily reported that 2,300 police were dismissed.

Saturday will see Turkey hold a major programme of events to mark the coup attempt, blamed by the authorities on US-based Muslim preacher Fethullah Gulen.

The decree, published late Friday in the official gazette, said those sacked were "linked to terror organisations, or groups determined to have been acting against the state's national security".

A former Istanbul governor was among those dismissed. The decree also stripped medals from Hakan Sukur, the retired Galatasaray and Turkey national team footballer.

Once one of the country's top sporting heroes, Sukur powered Turkey to third place in the 2002 World Cup where he scored the fastest goal in the competition's history.
