Do not preheat the oven. Grease 26cm tube cake tin and line bottom with baking parchment.
Sieve together the flour, baking powder and salt. Set aside.
In a large bowl, beat the butter, margarine and sugar on low speed for 10 minutes. Add the eggs one at a time, blending well after each addition. Alternately add the flour mixture and milk, mixing well. Add the vanilla and lemon extracts.
Pour batter into the prepared tin. Set the oven temperature to 180 C / Gas 4. Bake for 1 hour and 20 minutes or until a skewer inserted into the middle of cake comes out clean. Allow cake to cool in the tin for 1 hour. Remove to a cake rack and cool for at least 3 hours.
