The European Union has set out its guidelines for the next stage of negotiations on Britain's withdrawal from the EU, which is due to take place on 29 March, 2019.
After securing agreement last year on the key separation issues - citizens' rights, the border on the island of Ireland and Britain's financial settlement - the two sides are now seeking to agree a transition and future trade deal.
29 January
The EU agrees its guidelines for negotiations on a transition period which it says will run from exit day on 29 March, 2019, to 31 December, 2020.
British Prime Minister Theresa May asked for an "implementation period" of around two years after Brexit to provide continuity while new arrangements on the future relationship are established.
Brussels made clear that Britain would have to accept the bloc's laws despite not having any policy-making power, in return for continued access to the EU's single market.
Both sides hope to strike agreement on the transition by the end of March.
30 January
Britain's unelected upper House of Lords holds its first debate on the EU (Withdrawal) Bill, which would formally end the supremacy of European law in Britain.
Peers have promised to try to change the draft law, which has already led to one government defeat in the lower House of Commons.
Bills relating to Britain's new trade, customs and immigration systems after Brexit will proceed through parliament over the coming months, posing a headache for Mrs May's minority government.
