Why are investors worried by US deal?

Michelle Fleury reports on the negative market reaction which followed the deal to avert any future US government shutdown.

The Republican-dominated House of Representatives has passed a two year compromise spending plan designed to prevent future shutdowns, like the one that forced the government to close for two weeks.

Final passage is expected next week in the Senate - but it does not tackle that other thorny issue of America's borrowing limit or "debt ceiling".

So it is not seen as good news for investors, as Michelle Fleury reports.
