The housemates will have to put their backs into the first live task of Big Brother 4, as they'll be pitted against each other in a tug-of-war competition this evening.

In tonight's task, the housemates will have to elect a leader to choose two teams who will take each other on in the tug-of-war bout; the leader will then be called into the diary room to receive further instructions, with the winning housemates earning themselves a 'special reward' from Big Brother.

The garden has already been marked out with white lines to indicate the rope line and its halfway point, which led to suggestions from some of the housemates that a tug-of-war competition will be taking place this evening.

Details of the 'special reward' are not clear, although speculation abounds that the winning housemates will either be shown into a hidden room inside the house, or that one or more housemates will be made 'Head of Household'.
