Dont be afraid to push it hard down, you spark is probably traveling the easiest route, down the plug and out to the cylinder head giving you a weak spark. There is a thread on top of the plug, and a spring clip inside the cap PUSH HARD and you should feel the cap going over the threads. You may have to fiddle it to get it central, but it will go.

It still dont work but i have noticed that there could be a problem with the spark plug. I dont want to sound stupid but should the plug be just like a car spark plug because the hook bit is missing is it possible its broke off leaving the screw part ??

Yes it should have a 'hook bit' just like a car.
If you have to replace it get an NGK CR7HSA or or HIX avaliable from bike shops or Halfords.
