CGT rules - transfers to spouse

What exactly are CGT rules for transferring shares to spouse? I thought that they transferred at original price paid by first owner - so spouse paid CGT on total gain between original purchase and the final sales proceeds when the second spouse sells. Article in todays Daily Mail - page 4 - talks about stock exchange chief transferring shares to her husband and only having to pay 10% tax on the increase in value between date she bought and date of transfer. I presume the 10% is because the shares are in company she works for, so a business asset - but would she have had to sell the shares publicly and get her husband to buy them bsck on open market to achieve this? The way the article is written, it suggests that she transferred them by gift and "City experts said it meant....she will only pay 18 per cent of any increase in the share's value, because she has 'locked in' the tax on the initial gain". Is this true -that by transferring prior to end 5th April the gaain to that point becomes certain in tax terms and would be at only 10% for business assets?
