The former Bond girl was victorious last year (09) when officials overturned a previous ruling and agreed to give 36,000 Nepalese soldiers and their families the right to live in the U.K.
Britain's defence minister Kevan Jones criticised the actress earlier this month (Mar10), claiming there had been a "deathly silence" from her ever since - but he issued an apology to Lumley on Monday (29Mar10), insisting he had not intended to cause offence.
Now Lumley has blasted her critics for telling "lies" about her involvement in the campaign, and for suggesting she was used for publicity purposes.
She says, "Over the past month or so, articles have been appearing which must have put doubt in the hearts of those who supported the Gurkhas Justice campaign last year, and the wonderful policy which was won for Gurkha veterans to be allowed the right to come and settle in this country.
"Today, what we want to do is to call on the Prime Minister to affirm that the policy is still one that he completely supports... and also for us to say to the people of this country: What you did was to back a just cause and that we have not stopped working solidly for the Gurkhas, even though we've been doing it in quiet, as we promised to the Prime Minister last year.
"It has been suggested that I was somehow parachuted in, took the headlines, and ran. I consider that a slur. The people who made these accusations must know them to be untrue."
