Drain off some of the oil via the drain plug in the sump.
If you are not able to do this you can buy a pump with a length of hose which is inserted down the oil dipstick tube. You then simply suck the oil from the engine.
Go to this site to see what I mean.

You can probably get something similar from local motor factors, tool shops etc.
I would not run the engine until the excess oil is removed, you will ruin the engine. You may already have blown seals.
