The 87-year-old former Prime Minister suffers from declining health and she is rarely seen in public.
But the Wrekin MP visited the Baroness recently at her home in central London and reported that she was in good health.
He said: "She is in good health overall and still has her sense of humour and quick mind."
He added: "Lady Thatcher knew how to lead.
"Not everyone agreed with her but at least she meant what she said.
"She played a huge part in ending the Cold War and bringing down the Iron Curtain.
Baroness Thatcher was Britain's longest-serving prime minister in more than a century and the only woman to hold the post .
She has suffered a series of mini strokes in recent years which, according to reports, has led to some short term memory loss.
Nowadays, Lady Thatcher spends most of her time in her elegant four-storey home in London's Belgravia with a trained private nurse.
But she has been spotted out and about recently according to reports, including a visit to a London Park.
Baroness Thatcher visited Shropshire in 2006 when she attended the opening of the National Cold War Exhibition at the RAF Museum Cosford, near Albrighton.
