Margaret Thatcher's most memorable visit to East Yorkshire came in 1980 when she visited pharmaceutical company Smith & Nephew.
The then Prime Minister, who has died of a stroke today at the age of 87, visited Hull at a time of national unrest and industrial action.
As many as 1,000 workers walked out of the factory in protest prior to her visit.
Thatcher brushed it aside, saying: "I think it's a pity - but how nice it is to see so many here."
She praised the firm's revolutionary plastic skin dressing: "Yes, it's British - it's been developed by this firm, and there's nothing like it anywhere else in the world."
A day or two before she came Reckitt and Colman had asked Downing Street to call off her visit to them during her trip.
This followed a strike by more than 1,200 white collar workers at Reckitt's three Hull factories, and the prospect of a mass demonstration by trade unionists and students.
It was her only visit to Hull while Prime Minister.
On the previous evening, March 13, 1980, Mrs Thatcher had been guest of honour at a reception for Conservative Party workers at Cowick Hall, near Goole.
It was hosted by Sir Paul Bryan, Conservative MP for Howden at the time, and Douglas Brown, chairman of the Yorkshire Conservatives.
The following morning, she toured a mining district near Selby and a glucose factory at Howden.
She went on to lunch with party workers at Cottingham Civic Hall, where she faced a protest by BAE workers.
Margaret Thatcher's other memorable visit to the region came in 1992, two years after her resignation from the premiership.
She toured Beverley in the run-up to the general election to campaign on behalf of Tory candidate James Cran.
During her visit she also toured Swift Caravans' base in Cottingham.
