Short money is the funds received by opposition parties that win two or more seats in the House of Commons at the general election or win one seat and gain more than 150,000 votes.

The Opposition parties are rivals of the party (A) that means the rival get the money from winning the seat not the party (A). Why is it considered 'party (A) fund'?

No. I think you've got the wrong end of the stick.

You need to wait for someone who understands these terms used to describe the British political and governmental system better than I do.

Opposition parties are the parties that are not in power. They are opposed to "the government". Typically only one party forms "the government".

So the definition of "short money" applies to all parties that are not part of the government. (I think we would call that "the administration" in the U.S., not the government.)

Wait for a better explanation.



Here's some more background.

After a general election, the party that winds the most seats is called the governing party.

The other parties are called the Opposition parties.

Some of the Opposition parties are very small, and have very little money, and win only a few seats. In a healthy democracy, the governing party gives the Opposition parties some funding to help them to continue to exist. A true democracy needs more than just one party.

This is just a quick outline of how it all works, in Canada for example.
