Scotland v England, Ireland v Wales
Led by Bill Beaumont in this Calcutta Cup match, England are chasing their first Grand Slam since 1957. Scotland will need all the attacking flair of Andy Irvine and Jim Renwick if they are to counter the all-round team work and power of England. Ireland, with Ollie Campbell only two points away from a championship season record of 39, will hope to keep Terry Holmes and the Welsh backs under pressure from the start.

Granite islands set in a rolling ocean of grassland. Massive outcrops of Africa's ancient bed-rock dwarfed by the immense surrounding plains of the Serengeti. They call them kopjes. They are an intriguing stage on and around which a drama of African wildlife is played out year by year.
The rocks are a hunter's lair for lion and cheetah. There's water, too, in secret pools abundant with life. and nourishing huge trees and exotic plants that are browsed by giraffe and klipspringer.
But it is creatures like the curious hyrax, the colourful and acrobatic agama lizard and the huge verreaux's eagle that, by never deserting these islands even at the driest time of year when the plains are empty of gazelles and wildebeeste, make these remote rocks a refuge for all seasons.
