SEOUL Prime Minister David Cameron on Thursday condemned as unacceptable violence at a demonstration in London against his government's plans to increase tuition fees for students.
Protesters broke into the headquarters of Cameron's Conservative Party on Wednesday, smashing up the glass reception area.
Cameron saw television images of the violence when he arrived at the G20 summit of world leaders in South Korea.
"I saw pictures of people who were bent on violence and on destruction and on destroying property and that is completely unacceptable," Cameron told the BBC in an interview in Seoul.
"And to make sure that that behaviour does not go unpunished and we need to make sure that we don't, as the police put it, see scenes like that on London's streets again."
It was the first violent protest against 81 billion pounds of spending cuts ordered for the next four years by the Conservative-Liberal Democrat coalition to tackle a record budget deficit.
Until now Britain had seen only muted anti-austerity protests compared with those which have rocked other European countries such as France and Greece.
Police made 32 arrests and said 14 people were injured, including seven officers. Some rooftop protesters hurled placards and other small objects onto the police below them.
Cameron said that he did not foresee a return to the 1980s when a Conservative-government led by Margaret Thatcher faced a series of violent protests by striking miners and over a local tax, as well as inner-city riots.
"I think there's a very big difference to the 1980s," Cameron told Channel 5 in a separate interview.
"This time we have a coalition government, we have two parties that have come together in the national interest, that's trying to take the country with us as we do difficult things in terms of dealing with the debt and the deficit," he added.
"I think most people understand we have to take these steps, we have to get Britain out of the danger zone."
Under the plans for universities, the coalition plans to treble fees for students to a maximum of 9,000 pounds per year -- shifting the burden from the state to graduates.
