The UK government has no overall Brexit plan and a strategy may not be agreed for six months, a leaked memo prepared for the Cabinet Office suggests.

The memo - obtained by The Times and seen by the BBC - warns Whitehall is working on 500 Brexit-related projects and could need 30,000 extra staff.

However, there is still no common exit strategy “because of divisions within the cabinet”, the document adds.

The government said it “didn’t recognize” the claims made in the memo.

UK’s Transport Secretary Chris Grayling said he had “no idea” where the report came from.

Prime Minister Theresa May hopes to invoke Article 50 - beginning the formal two-year process for leaving the EU - by the end of March next year.

However, BBC political correspondent Chris Mason - who has seen the memo - says the document shows how “complex, fraught and challenging delivering Brexit will be”.
