UK stock markets have closed for the Christmas break in an upbeat mood.
The FTSE 250 jumped 1.15% to 20,531, hours before the Brexit trade deal with the EU was announced.

Asian markets closed positively with Japan's Nikkei gaining 0.54%, while markets in Australia, South Korea and Singapore also saw modest rises.
Sterling has always been the most reliable of Brexit trade deal sentiment - the pound rose against the US dollar yesterday and continued that rise this morning.
It started the week worth $1.34, dropped to $1.32 as hopes of a deal faded, and this morning climbed to $1.36.
The stock market reaction today has been muted - the FTSE 100 was barely changed this morning, but much of the reaction to the looming deal took place yesterday.
The FTSE 250, a stock market index that is regarded as more representative of the UK economy, climbed nearly 2% on Wednesday.
Lloyds Bank, which investors have come to see as a bellwether of sentiment towards a trade deal, rose 7% yesterday and another 6% this morning.

Why do market movements affect me?
If your reaction to "market movements" is that you are not directly affected because you do not invest money, think again.
You are likely to be one of the millions of people with a pension - either privately or through work - who have their savings invested by pension schemes.
As much as £600bn is held in defined contribution pensions at the moment.
Pension savers mostly let experts choose where to invest their money to help it grow.
But that means the value of your savings pot is influenced by the performance of the investments.
So rises or falls in shares can affect your pension and effectively your savings, which is why you are affected by major market movements.
However, it's worth bearing in mind that pension savings, like any investments, are usually a long-term bet, so short-term market fluctuations are not something to panic about.
"There's a huge difference between knowing you're connected to the stock market and panicking about it," says Sarah Coles from investment platform Hargreaves Lansdown.
"Stock markets always go up and down over the short term," she adds. "It's important to bear in mind that investors have lived through major ups and downs in the past and come out the other side."
