Mrs Thatcher has got a lot of answering to do Labour leader Neil Kinnock

The prime minister and the rest of the Cabinet have been backing a deal with an American firm, Sikorsky Fiat.

Calls for Mr Brittan to go have been mounting. Last night, he faced them from his own party, at a meeting of the influential Conservative backbench 1922 Committee.

This afternoon, Mr Brittan went to see Mrs Thatcher and offer his resignation. He left Westminster stony-faced and went straight to Kings Cross to catch a train to his Richmond constituency.

Resignation

He said nothing to reporters gathered at the station - the news of his resignation was announced only after the train had left.

Mr Brittan spoke to journalists on arrival in York.

He said: "I think that any minister must have, if he is to work effectively, the full confidence of his colleagues. This morning I made inquiries and I felt that I did not have that confidence and I therefore asked to see the prime minister to tender my resignation."

In a statement, Mrs Thatcher said she had tried to persuade Mr Brittan to stay in the Cabinet. She hoped it would not be long before he returned to high office to continue his ministerial career.

Labour leader Neil Kinnock said: "Mrs Thatcher has got a lot of answering to do to questions that she has dodged or avoided or ignored in the past several weeks."
