The campaigner, who has stage four lung cancer, argues the groundswell of support across the country shows the "current law is cruel and must be changed". Our petition has become the most popular on the Government's official website and has already secured a landmark debate next Monday, April 29.
Dame Esther, 83, said: "This petition shows 200,000 reaI sons why it is time for MPs to listen to the voice of the people.
"Sadly won't be able to attend next week's debate but I will be watching it from home.
"Although the debate can't change the law, I hope that so many powerful voices will take part that the Government will be forced to pay attention and make time for this life and death issue to be thoroughly investigated.
"So many of us feel that the current law is cruel and must be changed."
The Daily Express Give Us Our Last Rights crusade, launched two years ago, is leading calls for a change in the law to allow assisted dying for terminally ill adults.
It received a major boost when Dame Esther bravely revealed she had registered with Dignitas in Zurich, Switzerland, after her diagnosis in January last year. Thousands have since rallied to back her call for the right to die and, earlier this week, the Childline founder joined a private meeting with the Express and MP Tonia Antoniazzi, who will open the petition debate.
Dame Esther, a lifelong campaigner, said she surprised was the outpouring of support she received after JR 135 speaking about her situation last December.
She said: "When I mentioned it in a TS podcast, I had no idea it was going to get the traction it did. It just seemed to resonate with so many people.
"The fact that the Express and Dignity in Dying picked it up is a reflection of the fact that as you get older, and circumstances mean that you witness or know of the deaths of people close to you, you become aware that as wonderful as palliative care can be, it doesn't always create the sort of pain-free dignified death.
"When it doesn't work and people are longing to die and say so to those around them, and everybody is helpless and can't give them what they most want, then that becomes the abiding memory." Fear that her family would be left with horrific memories of her final days and hours led her to contact the Swiss assisted dying clinic, Dame Esther explained.
She added: "If the last memory of those you love is you struggling, in pain, in acute discomfort with a loss of dignity, maybe asking to be helped to die, that memory acts as a barrier to all the positive memories.
"It's not how I want my loved ones to remember me.
"That undoes for me the joy of having a family that I've had so many happy times with, if all they can remember is the pain." However, the grandmother of five's plans were dealt a blow when she realised her family would risk prosecution if they accompanied her to Zurich. Dame Esther said: "I signed up to Dignitas and then discovered that they couldn't come with me.
"Even if I could afford the air fares for all of us, it would put them at risk of a police investigation - even though I'm not known for keeping my views quiet." This week's meeting was part of Ms Antoniazzi's research ahead of the crucial debate. The Welsh Labour MP, below, also opened the last Westminster Hall debate on assisted dying on July 4, 2022.
Then, Ms Antoniazzi broke down in tears as she read heartbreaking stories of people who suffered indignity at the end of their lives.
She shared examples including the case of Gareth Ward, whose father Norman took his own life after his terminal prostate cancer unbearable
Dame Esther said it was important that the voices of people like Gareth who have been forced to watch loved ones suffer - are heard next week.
The That's Life! presenter added: "Painful though it is, if we can actually describe what it's like watching some- one die in agony, someone you love asking for assistance and is being denied it, that's what people need to understand." Arguments against assisted dying were also discussed.
Opponents often say that if the palliative care available was improved in the UK then assisted dying would not be needed.
But Dame Esther said it was clear that "the best palliative care in the world cannot give everyone a painfree, dignified death". She urged medics to read a recent Commons Health Select Committee report which found the introduction of assisted dying in other countries had often come with improvements to end-of-life care.
Dame Esther explained: "We aren't criticising palliative care practitioners - we need them and we value them.
"But, the fact is, that it is not always possible to give people the death that they choose themselves.
"We believe that assisted dying being legalised under these circumstances would strengthen what they do, their very important branch of medicine. I know that some doctors say, 'I don't want to do this. This is not what I trained to do'. Just as we, the patients, should be given the choice, doctors should have the choice." Dame Esther paid tribute to other public figures who have supported the assisted dying campaign, including The Great British Bake Off judge Dame Prue Leith and TV presenter Carol Vorderman.
And she revealed that of the deluge of messages that she has received, only one opposed her decision and said assisted dying was a crime for religious reasons.
The TV legend said: "If your religion precludes you from having an assisted death, or for any reason you oppose it, that's your choice.
"All we are asking is that people who make a different choice should also be allowed to have the death that they wish." to Repeating her demand for MPs to be given a free vote on the issue, the broadcaster urged politicians "respond as human beings and think about their own loved ones, their parents, their children".
Dame Esther added: "If they had a terminal illness which caused them such intense pain they wanted to die, what would it be like to be prevented from giving them the pain-free death they are begging for?" In the meeting, Ms Antoniazzi told Dame Esther and the Express that the debate was sure to be a "pivotal moment".
The MP added: "I feel very strongly because I'm probably of a similar age to your daughter and my mother has been very unwell.
"I hope that it has been good for your family to be able to talk about it.
"One of the things we do need to talk about as a society is dying - we don't do it well enough."
