Unlike many other places, most STARs into Heathrow terminate at a VOR with a hold: unless further clearance is provided, you automatically enter the hold there. While arrival transitions connecting these VORs to the ILSes are published, they are rarely used, ATC preferring vectors most of the time. Consequently, it is typical to be instructed to leave the VOR on a heading, either after exiting the hold or immediately upon first overflying the station, before receiving further vectors toward final approach.
