Sir Elton John has criticised the current state of the UK government, branding politicians “untrustworthy”.

The singer said: “Its tragic when you lose faith in everybody that’s a politician.

“It seems to me there’s nobody you can trust in the British system at the moment and that’s a horrible thing. I’m so disillusioned with politics in Britain.”

His comments on the expenses scandal are in stark contrast to those made by broadcaster Stephen Fry.

Fry called the public outcry over the exposed claims “revolting”, adding: “There’s nothing worse than the British in one of their fits of morality.”

Sir Elton has also spoken out on the AIDS crisis in the last few weeks, attacking world governments for their failure to address the epidemic.

Speaking at the 2009 BIO International Convention in Atlanta, US, the star said he was moved to start up his own AIDS charity after feeling guilt at not speaking out during the 1980s, when a number of his friends were killed by the disease.
