Churchill therefore had a slender majority in the war cabinet, but so much depended on Chamberlain who was always somewhere between Churchill and Halifax. Churchill decided to invite Sinclair to attend the war cabinet after the Sunday meetings. His argument was that Sinclair as leader of the Liberal Party should have a say, but in fact Sinclair was an old friend on whose support he could rely. Even with a four to two majority around the table, Churchill could not risk both Chamberlain and Halifax resigning as that would bring the Conservative majority into the equation and, almost certainly, an appeasement government like the one that would soon surrender in France. He had to tread very carefully, therefore, until he could believe in Chamberlain's eventual resolve.
