Finnish MEP Laura Huhtasaari took to Twitter to share a video about the opportunities Brexit offers - including the chance to boost the UK's steel industry. She wrote: "Before the EU, the British did better."
Ms Huhtasaari's tweet is her latest show of support for Brexit.
Speaking last month before Boris Johnson struck his trade deal with Brussels, the Finnish MEP hit out at the bloc's stubbornness in negotiations.
Speaking in the European Parliament, she said: "Why is the EU so unattractive that Norway and Switzerland don't want to join?
"Why does the UK want to leave? Has the EU looked in the mirror to actually see what is going on?
"The UK has already concluded 60 trade agreements but it seems impossible for them to conclude one with the EU.
"They want to take back control of their borders, their laws and their fishing waters."
