European shares closed higher on Tuesday as investors shrugged off the U.S. government's first partial shutdown in 17 years, and as fears eased of a government collapse in Italy.
The pan-European FTSEurofirst 300 Index closed provisionally up 0.6 percent at 1,254.36 points, after U.S. lawmakers failed to reach an agreement on the federal budget by the October 1 deadline. This triggered a partial government shutdown that left an estimated 800,000 federal employees facing temporary unpaid leave.

"The risk tone improves somewhat as investors take the view that a partial shutdown, if resolved quickly, will do little damage to the overall health of the U.S. economy. That does however mean that we will need to hear the right sounds out of Washington to feel confident enough that the shutdown will not damage economic growth," Joe Rundle, head of trading at ETX Capital said in a research note.
