They laid down in the road in front of the gates to the commons and when asked by the police to move, they were adamant they were staying put.
I spoke to their organiser and asked politely if they could let the Taxis enter the square and explained what we were protesting for.
The trouble for us was the fact that private traffic was caught up and Taxis were finding it difficult to enter the square. Which was a shame as I had got there early and spoke to the inspector in charge at the briefing and he assured me that there would be no problem with cabs gaining access.
After about half an hour, the ladies got up and decided to march around the Square, allowing Taxis full access.
So although a little later than planned, again we managed to fill Whitehall, Bridge Street, Broad Sanctuary, Great George Street and the Square itself.
A number of volunteer Cabbies broke ranks to help out with disabled passengers, and all returned to the protest after giving their services free of charge.
It's drivers like these that make me feel proud to be a London Cabby, well done ladies and gents.
Sean Paul Day turned up with a film crew....more about the later.
We also spoke to a BBC news unit, who had come from BBC Northern Ireland office, to film the Ladies protest about their pensions.
We spoke about our disappointment that the BBC London news had ignored our protests over the last 18 weeks.
Also in the Square today was Tory Leadership hopeful Rory Steward, who spoke with quite a few drivers. He was outraged when told that Sadiq Khan had refused to meet with Lord Palmer's group of Peers to discuss our campaign "Where Buses Go, Taxis Go".
