LONDON - The United States has been downgraded from a "full democracy" to a "flawed" one in an annual ranking compiled by a British think tank, which cited an erosion of trust in government, AFP reported.
New US President Donald Trump capitalised on such long-standing problems in the system in his election campaign, said the Economist Intelligence Unit, part of the group which publishes The Economist weekly magazine.
"The US, a standard-bearer of democracy for the world, has become a 'flawed democracy', as popular confidence in the functioning of public institutions has declined," the EIU said in its 2016 Democracy Index report.
"This has been a long-term trend and one that preceded the election of Mr Trump.
"By tapping a deep strain of political disaffection with the functioning of democracy, Mr Trump became a beneficiary of the low esteem in which US voters hold their government."
It said worsening income inequality, the "ideological entrenchment" in Congress resulting in deadlock, the financial crisis and repeated federal government shutdowns were behind the erosion of trust in the United States.
The ninth annual index report said Trump's election in November and Britain's vote to leave the EU in June were expressions of deep dissatisfaction with the status quo.
It said the relatively high 72 per cent turnout in the Brexit referendum was because people believed "their vote could change something for once".
The backlash against the establishment was a consequence of democratic failings, not a cause, it said.
European ruling elites are facing a growing revolt and a "full-blown legitimacy crisis" - and apart from dismissing voters as deluded, have shown "little inkling of how to respond".
The message for political leaders facing election in 2017 is that marginalised voters do no share the elite's values and will "look elsewhere" if mainstream parties do not give them a voice, the report said.
The index ranked 19 full democracies followed by 57 flawed democracies, then 40 hybrid systems and finally 51 authoritarian regimes propping up the list.
Norway, Iceland, Sweden, New Zealand and Denmark topped the index while Britain came in at No. 16 in the full democracies list.
Under the flawed democracies list, the United States came in at a joint 21st with Italy. Singapore was also in the same rankings list, coming in at No. 70. Other countries on the same ranking included Japan at No. 20, France at joint 24th with South Korea, India at No. 32, Indonesia at No. 48 and Malaysia at No. 65.
Thailand, Cambodia and Myanmar were ranked in the hybrid systems list, coming in at 100th, 112th and 113th respectively.
Meanwhile Russia and China came in under the authoritarian regimes list, at No. 134 and No. 136 respectively.
North Korea came 167th and bottom, below Syria, Chad, Central African Republic and Equatorial Guinea.
