Demonstrators begin their march in London to protest against government spending cuts Saturday. A quarter-million mostly peaceful demonstrators marched through central London against the toughest cuts to public spending since World War II, with some small breakaway groups smashing windows at banks and shops and spray painting logos on the walls. Commander Bob Broadhurst of the Metropolitan Police confirmed that more than 250,000 people had marched peacefully, but said around 500 had caused trouble in London's main shopping streets. (AP) __
