Jayne Sullivan wants supporters at a meeting with Dr Gibbons

Mother-of-two Jayne Sullivan, 45, is to resume her demo at the new assembly building, the Senedd, on Wednesday.

She has called for a meeting with health minister Dr Brian Gibbons to ask for an assurance that every patient who needs the drug will have it.

On Tuesday, AMs voted to speed up the process of approving new drugs.

The governing Labour group backed a Liberal Democrat motion on speeding up the approval of new drugs on the NHS.

Health Minister Brian Gibbons told AMs he "expected" local health boards all over Wales to approve the drug.

With regard to Herceptin, it is now readily available in the north and the south (of Wales), but there are two authorities in the west still holding out Jayne Sullivan

It means women with breast cancer could have the drug - only available in the late stages of the disease - earlier in their treatment.

Some local health boards (LHBs) will fund the drug despite the fact it will not be licensed in the UK to treat early stage breast cancer until March.

Ms Sullivan spent her first night at home on Tuesday following a seven-day protest in the foyer of the former assembly building, Crickhowell House.

During that time she repeatedly refused a private meeting with Dr Gibbons unless it was in public, but has now changed her mind, on the condition she can bring some of her supporters with her.

She told BBC Wales on Wednesday: "There was an awful lot woolly political-speak yesterday in the assembly but, what I can see of it as a layman, the assembly admitted that there was a postcode lottery.

"With regard to Herceptin, it is now readily available in the north and the south, but there are two authorities in the west still holding out."

It is still not resolved if the 22 local health boards in Wales will automatically prescribe Herceptin to women in the early stages of breast cancer.

At present, the 10 local health boards in south east Wales - including Ms Sullivan's own in Cardiff - have said patients who meet the criteria can have the drug.

A further eight say it will be available, but on a case-by-case basis. The remaining four health boards in mid and west Wales say they are reviewing their position.

'Postcode lottery'

Earlier in the day, Ms Sullivan led a march of more than 100 people to move her protest to the Senedd but said she will now only continue it during the day.

She said: "My own health started to deteriorate and that was purely due to the air conditioning and I have to remain strong for the ladies in the west.

"I thought by coming home during the night I could return to the assembly today and be just as forthright as I have been over the last week."

She said she wanted Dr Gibbons to say "in terms that I can understand and the people of Wales can understand that there is a post code lottery, that north and south are now providing this drug and it's not available in the west".

"In this situation, and it's very specific, a woman like myself, her back is against the wall, " she said.
