The campaign for the annual Bank Holiday Monday in late August to be known as Margaret Thatcher Day will be debated in Parliament again this afternoon.
The Bill is sponsored by Conservative MP Peter Bone. The Wellingborough MP was a staunch supporter of Baroness Thatcher who was brought up as Margaret Roberts in Grantham.
She was the first and so far only female British Prime Minister from 1979 to 1990 and Conservative Party leader from 1975.
