FLAG CLOSURE DAY-Monday will probably be the final day of the marathon flag debate in the Commons, with closure to be invoked to get approval for the flag in the top left corner. It would replace the Red Ensign, in the top right. In the bottom right is the Union Jack, which the special Commons committee recommended to show allegience to the Crown and membership in the British Commonwealth. The government is expected to seek its approval after the Commons approves the national flag. In the bottom left corner is the original maple leaf flag proposed by Mr.Pearson. Next is a revised version of the same flag, with more stylized leaves and broader blue borders. The third was proposed by artist A.Y.Jackson of the Group of Seven, its primary difference wavy horizontal blue bars. The new flag has a red maple leaf on a white background with red bars.
