When will the level of the pound fall below par with the Euro?

Interest rates to be kept low in the UK and interest rates to rise in the eurozone. Even with Greece's problems, it looks grim for the pound and imports of food could rise, also holiday makers going abroad will get less for their pounds. I can see inflation getting out of hand, back to the 70's when it reached 18% under the Tories then Has the light at the end of the tunnel disappeared.
