Grand slams unite to establish player council in attempt to diffuse prize money row

Move could be confirmed along with $100m US Open pot

Slams have been in dispute with players for 18 months

The grand slam tennis tournaments have agreed to establish a formal Player Advisory Council in a joint move aimed at diffusing the ongoing row over prize money.

The Guardian has learned that an agreement on the joint venture has been reached and could be confirmed on Wednesday as part of US Tennis Association’s announcement of this year’s US Open prize money, which sources involved expect to top $100m (£74m) for the first time.
