Here he recalls a painful experience.

Margaret Thatcher was the longest serving Prime Minister of the Twentieth Century. And she thought she more time to run - until her party - and in her eyes, the cabinet - deserted her.

The latest Conversation with the men (and one other woman) in the cabinet room when Margaret Thatcher resigned in November 1990. Today's guest is Michael Howard, who went on to be Home Secretary and Leader of the Tories. He was an ardent Thatcherite - who believes she would have gone on to win the 1992 election - but felt forced to tell her it was time to go because she had lost the support of her backbench MPs. He blames her exit on the man in charge of her leadership campaign - Peter Morrsion a Conservative grandee known for having an alcohol problem and now suspected of being a paedophile. 

Michael Howard was Home secretary and leader of the Conservative Party in the 2005 General Election. In 1990 when Margaret Thatcher fell he was her Employment Secretary - and an avowed admirer. But loyalty and admiration could not blind him to what he saw as fact - The Iron Lady had irretrievably lost the support of Conservative Party MPs. This forced him and many like minded colleagues - to give his candid view, one to one, that it was time go. She was, he recalls, like a wounded bird.

Her fall is especially galling as he's convinced she could have kept the top job - had the campaign in the leadership election been well run. Instead her campaign manager - the MP Peter Morrison - a man now suspected of being a paedophile - was "useless."  Simple competence, he believes, could have saved her - and set history on a different path

Andrew Turnbull, like other senior officials and her cabinet ministers, witnessed Margaret Thatcher tearfully read out her resignation statement to her colleagues in November 1990. As her Principal Private Secretary, he was also in the room for a series of one to one meetings beforehand where her colleagues told her the game was up. He recalls the events of her fall - and how the Prime minister had become incredibly preoccupied with foreign affairs - prompting the observation there was “more grandeur, less Grantham” - the town where she was born.

This is the latest in a series of conversations with those in the cabinet room when Margaret Thatcher resigned

Normal Lamont considers himself a Thatcherite. He thought his leader was right on Europe - unlike most of his cabinet colleagues. But even ideological affinity and personal loyalty could not trump the numbers in November 1990 - when the results came in he had to tell her it was time to go.

Perhaps no-one has experienced as bewildering a month in politics as Wiliam Waldegrave in November 1990. He was running the diplomatic effort to oust Saddam from Kuwait when he was suddenly promoted to the cabinet. Then just weeks later he was advising Mrs Thatcher if she could stay on. She couldn’t and he had a new boss - John Major. All just in just over three weeks. In the latest Big Ben History conversation on the Fall of Thatcher, he reflects on the longest month.

Lord Baker was Chairman of the Conservative Party at the time of Margaret Thatcher’s fall. He’d been given the job with specific aim of keeping in No 10 - and until November 1990 all seemed to be going fine. But Mrs Thatcher lost her temper with Geoffrey Howe in cabinet - he resigned - and gave a devastating speech to parliament calling for her to go. Even then he thinks she could have survived had she been willing to schmooze backbenchers, appoint a decent campaign manager, and face down her cabinet. Had she done so - her chairman thinks she would have gone on to an unprecedented fourth election victory

Previous episodes include interviews with politicians Tom King, John Gummer, John Wakeham, Lord Mackay - and officials Robin Butler, Caroline Slocock,Charles Powell, Barry Potter and Desmond Morris

Tom King was Margaret Thatcher's defence secretary. In November 1990 he was running the biggest deployment of UK troops since World War II for Operation Desert Shield against Saddam Hussein. He returned to find his boss on the way out and pleaded with her to pre-announce her departure so a more orderly exit could ensue.

James Mackay was a Scottish lawyer who by November 1990 found himself number two in the cabinet, reading a tribute to Margaret Thatcher - and helping her struggle through her resignation statement. 

Both say it's a meeting they will never forget.
