Probably rusted into the steel insert on the other end, drilling might be the only option, depending which end you drill from you need to drill out a good 10mm or more

Had the same on mine last year. Short of me wrecking it I decided it was best to just take it to my local bike shop and get them to do it. Only cost me 1/2 hr labour and they copper greesed it so it wont stick again.
