Is the Republican party the most right-wing major party in the world?

[afleitch]

All depends on semantics; our understanding of what a left wing and a right wing party changes. I would say the Tories are to the ‘right’ of the GOP on some economic issues, in the same way the Lib Dems are to the right of the Tories also on issues of trade and the economy but have never (rightfully) been considered 'right wing'. I would consider Obama to be a conservative president in economic policy in relation to his predecessor.

On social issues, the GOP is to the right, and tending right of nearly all major western political parties. It’s worth noting however that the increasing social progressiveness of right of centre parties in Europe is recent and reflects changing social attitudes. The GOP however has tried to buck the trend (or at least not move on from a position they held that is now out of date) The only parties that tend to try and counter social change in Europe are parties we would consider to be far-right.
