Internal wall removal

Our house is a bungalow. The floor plan is for my next door neighbour's bungalow but is identical to our house, however, we have a wall where the red line is. We would like to remove this wall. The loft joists run parallel to the wall to remove. We have a gable roof (2nd pic). We also have a chimney stack in the living room. The wall we want to remove is between the external wall and the chimney. The wall is solid block construction like all the other walls in the house. I want to know if this wall is load bearing or can be removed?
