Four years ago BBC News reported:

UK Prime Minister David Cameron has condemned the blockade of the Gaza Strip, describing the territory as a "prison camp". 

He also criticised Israel for launching an attack on a convoy transporting Turkish activists and aid to Gaza. Nine Turkish citizens died in the raid. 

He was speaking to an audience of businessmen during a visit to Ankara. ...

"Gaza cannot and must not be allowed to remain a prison camp," Mr Cameron said. 

"People in Gaza are living under constant attacks and pressure in an open-air prison," he said.
