British Airways share price falls on FTSE 100

The price swung almost 2 pct turning negative to 243.90 (-0.85 pct).

“It’s back to the 1970s, we have got hand-wringing from a weak prime minister,” said David Cameron, the Conservative party leader.

Mr Cameron demanded to know whether The Prime Minster would back BA in the strike and tell workers to cross the picket line.

The issue is a sensitive one since it would be harming relations with the Labour Party's biggest donor - the unions.

Mr Brown said he believed that the basis of a workable agreement had been on the table last Thursday and hoped it would be 'on the table' as the strike approaches on Saturday.

The strike this weekend is set to cost BA as much as £20 million destroying the £60 million cost-cutting target it set itself for the annual cabin crew budget.
