Chinese telecom firm Huawei has rejected allegations from former US Central­Intelligence Agency (CIA) chief Michael Hayden that it has been spying on the US government.

According to reports from the Australian Financial Review, Hayden said that it was his ‘professional judgement’ that the firm had delivered intelligence back to China.

Huawei has been alleged of sharing information about foreign telecommunications systems involved with the Chinese state, which the company said was "unsubstantiated" and "defamatory".

The UK government has also revealed plans to review Huawei’s participation in a cybersecurity centre.

Earlier, the US politicians claimed that the company had been posing a security threat over its alleged connections with China’s government and military.

The firm’s presence in the US has been alleged of enabling the Chinese government to spy on the US government and their products and services, posing a long-term security threat to the nation.

However, the Chinese firm criticised comments of US politicians and said that it should not be treated unfairly as it is a Chinese firm.

In May 2013, Huawei’s founder and CEO Ren Zhengfei dismissed the company’s involvement in the US cyber attacks.
