Markets rose on Monday as investors clung onto the possibility that Theresa May could get her Brexit deal approved in Parliament after EU leaders backed it over the weekend.
Reports that Italy might reduce its deficit requirement for its budget were also supportive to European trade.
David Madden, market analyst at CMC Markets, said: "News over the weekend that EU leaders endorsed the deal for the UK's exit of the bloc has also lifted investor sentiment.
"Traders are clinging onto the possibility that Theresa May will get enough support to get the deal approved.
"Mrs May will have an uphill struggle, but some MPs might vote in favour of it as they are too scared of no-deal scenario."
He said the pound is likely to hold-up in the absence of 'no-deal' chatter, however if opposition to the deal ramps-up it would "likely hurt the pound as it would open up the possibility of a no-deal situation."
The FTSE 100 closed 83.14 points, or 1.2%, higher at 7,036.
France's Cac was up 1% while Germany's Dax rose 1.5%.
The pound was down 0.1% against the US dollar to 1.281 US dollars and was down 0.1% versus the euro at 1.130.
Meanwhile, Oil prices recovered from Friday's lows on concerns of a supply glut.
Mr Madden said: "Oil has rebounded as short covering and bargain hunting has driven the price higher.
"The energy might be moving higher today, but the backdrop is still very negative. Concerns about supply persist.
"That being said, there is speculation that Opec (the Organisation of the Petroleum Exporting Countries) will announce production cuts at their meeting in December."

Shares in Faroe Petroleum rose 33.80p, or 27%, after its largest shareholder launched a £608 million takeover bid for the company.
