Ukraine and Russia have made significant progress on a tentative 15-point peace plan including a ceasefire and Russian withdrawal if Kyiv declares neutrality and accepts limits on its armed forces, according to three people involved in the talks. The proposed deal, which Ukrainian and Russian negotiators discussed in full for the first time on Monday, would involve Kyiv renouncing its ambitions to join Nato and promising not to host foreign military bases or weaponry in exchange for protection from allies such as the US, UK and Turkey, the people said.
