What is the case law in English case Ramsgate Victoria Hotel v Montefiore?

Ramsgate Victoria Hotel v Montefiore is a leading case in English contract law. It concerned the issue of when an offer may be terminated by revocation, and established the principle that an offer may be revoked at any time prior to acceptance, unless the offeror has promised to keep the offer open for a specified period of time or has made a binding contract to do so. In this case, Montefiore made an offer to buy shares in a hotel company, and the offer was held open for two weeks. Before the two weeks had expired, Montefiore attempted to revoke the offer, but the court found that he was bound by the contract because he had made a binding promise to keep the offer open for two weeks. The case established the principle that an offer may be revoked at any time prior to acceptance, unless the offeror has promised to keep the offer open for a specified period of time or has made a binding contract to do so.
