LONDON (Reuters) - Legislation to sever political, financial and legal ties with the European Union is vital to ensuring Britain leaves the bloc in an orderly manner, Brexit minister David Davis said on Thursday. Davis also said the powers offered by the EU withdrawal bill, which seeks largely to copy and paste EU law into British legislation, would allow the government to make sure the statute book works on the day Britain leaves the EU.  This bill is vital to ensuring that as we leave, we do so in an orderly manner,  Davis said at the start of a debate in parliament on the bill.
