Union Finance Minister Arun Jaitley on Monday said there were "various important issues to be discussed in parliament", and the Congress must allow the house to function."When more and more parties want to discuss issues (concerning the country), the Congress should also rethink on its strategy of disruption," the minister told reporters after both the houses of parliament were adjourned without conducting any major business."There are various important issues -- floods, legislation to be discussed (and) that's why we want Congress party, which is isolated, to let the house function," he said, adding that most of the other opposition parties were willing to debate issues and conduct business in parliament.
