Summary Box: UK cuts top income tax rate to 45 pct

TAX CUT: Britain's finance minister has cut the income tax rate for the country's wealthiest citizens — those making more than 150,000 pounds, or about $240,000 a year — from 50 percent to 45 percent.

STRINGS ATTACHED: A raft of new measures to prevent tax avoidance includes a new 7 percent charge on sales of homes worth more than 2 million pounds, about $3.2 million.

THE BIG PICTURE: Overall, the budget measures were neutral. The government is constrained by its primary plan to reduce borrowing and by credit agency warnings that the country's ratings could slip if its finances don't improve.
