Summit chairman Charles Michel tweeted "Deal" shortly after the 27 leaders finally reached an agreement at a 0315 GMT plenary session.

Euro Stoxx 50 futures were up 0.5%, while German DAX futures and FTSE futures gained 0.7% and 0.4%, respectively.

Hopes for a deal as well as positive data from an array of COVID-19 vaccine candidates had lifted the pan-European STOXX 600 index higher on Monday.
