Withdrawing from a sale agreement when the seller does note abide by the terms

If Form F of a property states that a property is tenanted to a certain date, and the date is incorrect, does the buyer have a claim to withdraw from the sale?

Essentially, I was told in writing that the tenant would "leave" the property by a certain date.

The actual notice was served to the client after the date of Form F being served, meaning that the tenant will be in the apartment for a further 12 months.

Do I have a right to withdraw as a buyer and have my deposit cheques returned?
